The Surprising History of Sin, Sex and the Soul

How Galen’s Philosophical Assumptions Became Augustine’s Theological Assumptions

Galen of Pergamum’s prolific work and incisive commentary changed the way the world thought about the human body. His influence extended for more than a millennium, building on the foundation laid by more famous philosophers such as Plato, Aristotle and Hippocrates. His father was an architect, but it was Galen who built the truly impressive edifice – a monument of work that would, perhaps unknowingly, influence another titan of philosophical thought.[1]

Like Galen in the world of medicine, Augustine of Hippo drew from numerous strands of philosophy and his chosen field, theology, to erect a prolific corpus that remains influential more than 1,500 years after his death.[2] Three centuries and a seemingly impassible divide between the Greek east and Latin west separated Augustine from Galen, but the latter’s reach was so extensive that he managed to bridge the gaps between even time, language and culture to influence the creation of Augustine’s signature doctrine.

Although Galen and Augustine both were master synthesizers, rendering futile any effort to attribute their ideas to only one strand of thought, Galen’s notions of gender, sex and the soul so radically reshaped the way future generations in the east considered those topics that they became influential pieces of Augustine’s thought, as well – and embedded themselves into the doctrine of original sin, itself a fusion of the church father’s ideas about the nature of sex and the fate of the soul. This connection, though not so obvious as to receive noticeable attention, remains clear and palpable, as this paper will show.

One idea about one sex

Not all of Galen’s works survive, yet those that do are a testament to his incredible proficiency: Temkin estimates they would fill roughly a dozen 1,000-page volumes.[3] Although Galen was foremost a physician, that title did not imply a neglect of the philosophical, as it might today. Indeed, his conclusions about men, women, sex and the soul – built through his interaction with ancient Greek philosophy – laid the foundation for Christian thought on the same subjects, coloring even the modern-day lenses through which we see these often-contentious issues nearly two millennia later. In a sense, we are all Galenists, adopting the legacy of the Father of Medicine, regardless of whether we intend to do so.

Galen’s conclusions can be summarized by what Laqueur calls the “one-sex/one-flesh model.”[4] In this model, most clearly articulated in his epic On the Usefulness of the Parts of the Body, Galen used the ancient Greek notions of the four basic bodily qualities – hot, cold, wet and dry – to affirm Aristotle’s contention that women are less perfect than men but claim the ancient philosopher had not carried the argument far enough.

The female is less perfect than the male for one, principal reason – she is colder. … A second reason is one that appears in dissecting. … All the parts that men have, women have, too, the difference between them lying in only one thing, which must be kept in mind throughout the discussion, namely that in women, the parts are within, whereas in men, they are outside.[5]

Galen notes the corresponding shapes of the penis and vagina, scrotum and uterus, and testes and ovaries – arguing that men and women therefore have the same reproductive organs, except the woman’s is turned outside-in. The reason for the difference, Galen says, is that women’s colder temperatures prohibit the organs from developing fully and moving outside the body, a phenomenon he likens to the nonfunctioning eyes of moles.[6]  These two things – the colder temperature and the subsequent incomplete development of the reproductive organs – show women to be imperfect versions of men, according to Galen. Instead of being divided by gender, men and women are in fact linked by it.[7] The argument about heat and cold forms the basis for Galen’s theory of gender, with significant ramifications for future Christian thought.

“Heat is nature’s primary instrument,” Galen argues, and that makes the man “more perfect” than the woman. Although he acknowledges the benefits of this difference between the genders for purposes of reproduction, even this makes the modern reader wince: “You ought not to think that our Creator would purposely make half the whole race imperfect and, as it were, mutilated unless there be such a great advantage in such a mutilation.”[8]

This notion of the essential sameness of the genders marred by the imperfection of the female carried over into the process of contraception, as well.  Aristotle believed only the male seed played a role in the generative process, something Galen rejected in On Semen, where he affirmed a place for female “semen” in the production of life – but nevertheless held to the idea that the male semen was warmer and therefore stronger and more perfect. “The female semen should always be ruled and indeed defeated,” Galen wrote, “and the male should prevail over it, so as to exercise by itself control of both kind and similarity.”[9]

In this way, Galen was no more than reflecting his culture, one in which male dominance was linked to social order, and subversion of the established gender roles was tantamount to anarchy. As Lacqueur notes, “The one-sex model can be read … as an exercise in preserving the Father, he who stands not only for order but for the very existence of civilization itself.” This had practical effects for the creation of the soul, as well: “Her sperma could not ensoul matter; his could.”[10]

Indeed, Shaw argues for the existence of a widespread ancient Greco-Roman belief that semen transmitted the soul, and that Galen held it, too.[11] The evidence is more complicated than she allows, but it is clear Galen and his contemporaries believed the semen did more than simply provide the physical blueprint for the next generation.[12] In Usefulness of the Parts, Galen posits that semen is borne by the innate pneuma,[13] and in On Semen, he calls the male seed “not matter only but also power” that “makes the major contribution to the animal’s material principle.”[14]

Galen is honest about the limits of his theorizing – he claims he doesn’t know what is the soul’s substance nor whether it’s incorporeal, as Plato claimed.[15][16] In the end, Galen appears to punt[17] – instead returning to firmer ground in his discussion of the pneuma, which he linked to the male semen. Yet the pneuma, if it’s not the soul exactly, seems to carry many of the hallmarks of it; Galen goes so far as to call it “the first instrument of the soul that resides in the brain, whatever its substance may be.”[18] Comparing the complex looping structure of the brain to those found in the male scrotum and female breasts, Galen argues that just as “Nature” provided those routes to hold the semen and milk for lengthy periods, so too the “complex labyrinth” of the brain is designed to house the pneuma.[19]

Galen therefore ties together the soul and the body in a thoroughly corporeal fashion, even if he avoids saying so directly, linking the soul to the physical semen, brain and pneuma of the body. Further, Galen tied the presence of pneuma with the body’s “innate heat,” according to Temkin, and described “weakness of the innate heat” as a cause of death. His description of the heat corresponds to both his description elsewhere of semen and the pneuma, indicating that Galen viewed these three things as closely linked, at the very least. Temkin argues these are all terms for the soul that a “medical materialist” like Galen would have found palatable.[20]

With semen tied so closely to the existence and reproduction of the soul, it should not be surprising that Galen viewed sexuality and morality through the lens of his medical training – and through the lens of Greco-Roman asceticism. In On Semen, Galen posits that too much sex weakens the body and draws “vital pneuma” from its reserves. Draining the body of semen is actually quite dangerous, Galen argues, because semen is the building block for the solid parts of the body, such as bones, and that “sexual intercourse is especially debilitating.”[21] Shaw provides the best summary of Galen’s broader ascetic worldview – his use of Stoic notions of self-control to discuss diet and sexuality – and the connection he made between the consumption of food for the regulation of sexual desire. In Galen’s world, sex had a connection to weakness and mortality – not just through the urge to repopulate in a low-lifespan era, but in the actual damage it could do to the human body.[22]

All of these elements – the essential sameness of the genders with an emphasis on female imperfection, the physical nature of the soul transmitted through the act of reproduction, and the ascetic lens through which to view sexuality and the human body – would prove to be highly influential in the ensuing centuries. Laqueur argues they “dominated thinking about sexual difference from classical antiquity to the seventeenth century.”[23] Although Galen’s work was not fully known in the Latin west until about 1000 C.E., Galenism as a set of medical and philosophical assumptions became the underlying basis for centuries of theological thought and – as a result – a fundamental piece of what Augustine inherited when he converted to Christianity early in the fifth century.

Galen in Cappadocia

Within 150 years, Galenism was the dominant medical philosophy of the Greek-speaking Roman Empire. By 400 C.E., the dominant medical assumptions in place east of the Balkans were those of Galen.[24] This was also the era in which Christian asceticism became a powerful force, and at least two of that movement’s most forceful advocates did so with a heavy reliance on Galen’s logic and language. Galenism was adopted into an explicitly Christian worldview by at least two bishops in the Asia Minor region of Cappadocia. Basil of Ancyra and Gregory of Nyssa each wrote treatises on the value of purity in the life of the Christian, using the same three themes articulated above: sameness of gender, physical nature of the soul and an ascetic connection of sexuality to the health of the body.

Basil’s treatise remains in some dispute. It was classified as a work of Basil of Caesarea until the early 20th century, and it has yet to be translated into English – or apparently any modern language. Scholars have generally found the work notable for its explicit description of bodily passions and sexual desire, according to Shaw,[25] but she argues behind the sensationalism lies the worldview of a physician influenced heavily by the works of Galen: “Basil has taken ideas about diet, digestion and sexual function from his medical training and applied them to daily life and training of one who chooses to live in perpetual chastity.”[26]

This isn’t to say Basil of Ancyra was influenced into asceticism by Galenic thought, but he used a Galenic framework to discuss the physical, sexual and philosophical components of asceticism. For example, Basil’s consideration of the link between sexual desire and the human need for procreation, while supported by a pair of scriptures, is little different from Galen’s own description.[27] More important for our study, however, is how Basil describes the creation of gender, speaking of a single “root” divided into male and female. As Shaw describes it:

In order to populate the earth, the Creator placed in the nature of each “fragment” of original being an ineffable desire for union with the other through intercourse. To this the Creator also added the physical pleasure of sexual intercourse and the strong affection felt for offspring. Subordinating the female to the power of the male and “taming” the male by the “pleasure” of the female, the Creator made the male active by nature and the female passive, since she was taken from the male.[28]

Basil again cites a scriptural basis for his views, but the creation story has been read through the lens of Galenic thought: “For knowing, as I suppose, that the substance from which she had created animals does not admit of perfect wisdom, Nature by adding a passionate pleasure to the use of the parts gave them in its stead the only thing which they could receive as an incitement to preserve and maintain the race.”[29]

The male, Basil writes, regains “in his very self, through intercourse, his own member. Thus two out of one and back again to one from two.”[30] Much as Galen was careful to leave room for a female role in the procreation process, Basil also does not subscribe to a fully male-dominated sexual theology. To provide the woman with a measure of power, God gave her “the power of sexual attraction over the male,” in Shaw’s words. Basil writes the male is a “prisoner of her pleasure,” and that this power of attracting a male sexually, while not unique only to the female gender, is an ingrained, created piece of her nature.[31]

Although they speak different languages theologically – Galen’s naturalistic focus contrasts with Basil’s reliance on the narrative of Gen 1-3 – they both describe the same features: A single gender divided into stronger (male) and weaker (female) components, with a failsafe in place to prevent total domination of the weaker. Basil then follows Galen’s teachings on diet to recommend ways for a committed virgin to diminish her sexual appetite, with the intention that eventually those elements that incite her to lust – and incite men to lust after her – will wither and die. In a remarkable passage, Basil explicitly praises those women who have successfully altered their physical appearance to become more like a man’s. There can be no doubt Basil considers this a better, more perfect state in which the woman should live:

Not only will she avoid beautifying herself, she will intentionally obscure her natural beauty. She must “make her look masculine and her voice hard, and in her walk and generally every movement of her body constrain the enticements of pleasure.” The “form” of the female body, which was made alluring at creation, is made “pure” through virginity and asceticism.[32]

Basil’s more famous colleague, Gregory of Nyssa, while owing much to Basil’s thoughts on asceticism, also was heavily reliant on Galen. Gregory, in fact, is explicit in urging his readers to “learn everything accurately … which those skilled in such [medical] matters have worked out in books” and follows that statement with an in-depth discussion of the human body that closely parallels Galen’s work.[33]

Gregory “demonstrates considerable medical knowledge,” Corrigan argues, and accepts Galen’s medically based revision of the Platonic tripartite division of the soul.[34] Gregory would certainly have been familiar with Galen’s one-sex model; indeed, his notion of gender and its relationship to the Genesis story hews even more closely to Galen than even his fellow bishop’s. As Brown argues, “He had no doubt whatsoever that the present division of the sexes into male and female formed part of the present anomalous condition of human beings.”[35]

Indeed, in On the Making of Man, Gregory states what Basil merely implied: that sexual differentiation – and therefore sex itself – was a product of humanity’s fall in the Garden of Eden: “Our whole nature … is, so to say, one image of Him Who is; but the distinction of kind in male and female was added to His work last” only because God, in his foreknowledge, knew intercourse would become necessary for humanity to procreate in its soon-to-be fallen state.[36] Gregory, therefore, Christianizes Galen’s one-sex model, turning Galen’s impersonal Nature into the personal God, yet both are described as having created a single gender, now divided in two, with the male more perfect than the female.

Gregory also follows Galenic assumptions about the soul. Although Galen’s speculation about the soul was rejected by Christians of his day,[37] Gregory adapted it into a more palatable philosophy, yet one that still hewed closely to the materialist notions of the medic. Gregory not only Christianized Galen’s biological assumptions, he did the same for Galen’s philosophical ones, as well. As Corrigan argues, “A medical/scientific view of body in soul … virtually codified later by Galen, comes into new focus because of Christian thinking.” The body has its own intelligence arising from its organic nature, Galen argues and Gregory affirms, and the soul is a part of that structure.

Gregory puts an end to any disproportionate primacy of soul over body. Because of his rejection of the pre-existence of the soul, soul-body/form-matter develop together from the beginning in an organic whole-formation that does not subordinate one to the other. … Gregory’s interest in medicine, in which he follows Basil and Galen, helps him explore the interconnectedness of psycho-physical processes in the body.[38]

In Making of Man, Gregory argues the soul is coexistent with the human fetus and grows with it. Then he describes a “supreme force,” housed in the brain, controlling the body. Galen called it the pneuma, the “first instrument of the soul,” but the men clearly are describing the same thing. Finally, Gregory concludes his argument with this statement: “The seminal cause of our constitution is neither a soul without body, nor a body without soul, but that, from animated and living bodies, it is generated at the first as a living and animate being.”[39]

Gregory, like Galen before him, does not specifically connect creation of the soul to the reproductive act, which would align with the traducianism first articulated by Tertullian in the west, but with such a materialistic view of the soul, he hardly needs to. By tying the soul so closely to the physical human body, Gregory leaves little room for any other explanation. If the body is created via intercourse, so must the soul be.

East and west reunited

Although a wide gap existed between the Greek and Latin worlds within the bifurcated Roman Empire, Gregory of Nyssa’s works were not unknown in the west. Indeed, Ambrose, the powerful bishop of Milan and a contemporary of Basil and Gregory, was one of the few Latin-speaking clergy who also knew Greek; his extensive library included the works of the Cappadocian ascetics, who helped him formulate what Brown calls a “singularly austere spirituality.”[40]

Ambrose was in fact the product of a pair of ascetic movements – the eastern, to which he had access through his library, and the western, which exerted a more direct influence through the works of Tertullian, Origen, Cyprian and others.[41] The interplay between these movements can be seen in the development of Ambrose’s own thoughts about sin and sexuality.

Christians in both east and west increasingly were turning to asceticism as the primary method of restoring the human body to its former paradisiacal state, focusing more intensely on human sexuality and gender differentiation. Elm puts this succinctly: “The more the body became the vehicle for salvation, the graver became the concerns regarding its fallibility and corruptibility, made manifest in its sexuality.”[42] Indeed, Ambrose was deeply concerned with the sexual fallibility of humanity and placed a strong, even overriding emphasis on virginity, to the extent that opponents accused him of promoting Manichaeism.[43] For Ambrose, the question of sexuality was addressed less through the story told in the first three chapters of Genesis but through the one told in the first two chapters of Luke. In his commentary on the third gospel, Ambrose hardens a position at which he has arrived only slowly[44] – and seemingly after engaging with the notions discussed most by the Greek Fathers. Ambrose’s position on two passages of scripture, mixed with the assumptions left him by Basil of Ancyra and Gregory of Nyssa – and, by extension, Galen and the Greek philosophers before him – led him to an extreme asceticism that followed to their logical extremes the western and eastern strands he inherited.

First, Ambrose inherited and embraced Origen’s belief in the requirement of a virginal conception for a sinless Christ. But in his commentary on Luke 2:23, Ambrose shifts Origen’s more straightforward reading of the text. The opening of the woman’s womb discussed in the verse, referring to Ex 13:12, appears to refer to the birth of a firstborn son; Ambrose instead sees it as the virgin womb’s reception of male seed for the first time.[45] The nature of human seed, a focus of the Greek ascetics, was now also the focus of Ambrose, and as he treads this eastern ground, the western bishop joins them in placing a heavy emphasis on the primacy of the male seed: “For no union with a husband unlocked the secrets of her Maidenhead, but the Holy Spirit poured unstained seed into her inviolate womb. For wholly alone of those born of woman was our Holy Lord Jesus, Who by the strangeness of His undefiled birth has not suffered the pollutions of earthly corruption.”[46]

Whether he realized it or not, Ambrose had applied Galen’s notion of female imperfection and the superiority of male seed to the conception of Christ – only the male seed could have been powerful enough to transmit humanity’s sinfulness.  Mary simply wasn’t strong enough to play a significant role in the creation of her son. With this interpretation of Luke 2:23 in place – that Jesus was sinless because of the purity of the male seed from which he grew – Ambrose turned to Ps 50:7 (“I was conceived in iniquity, and in sins my mother gave birth to me.”) to argue that sexuality itself was the way in which human sin was transferred.[47] The combination of these two passages highlights Ambrose’s mixture of western and eastern ascetic thought.

With a western background influenced by Origen and encratism, Ambrose was not content to simply argue for human sexuality as a consequence of the Adamic fall, as did Basil and Gregory. Rather, he saw intercourse itself – the implantation of the male seed – as the act transmitting human sinfulness. Although neither Gregory nor Basil developed this idea, it was the logical outgrowth of their philosophy. If the human soul was sinful from birth, as Ambrose believed Ps 50:7 said, and was inexorably joined to the physical body, as Galen, Basil and Gregory posited, then the natural conclusion was exactly the one Ambrose made: that sex transmits the sinful soul, and therefore human sexuality was the cause of Adam’s fall, remaining what Brown describes as an “ugly scar” on the face of humanity[48] and transmitting the effects of that fall through generation after generation:

The passions of pleasure are changeable and slippery, and are infected, as it were, with the poison of corruption. It is certain, then, that Adam, deceived by the desire of pleasure, fell away from the command of God and from the enjoyment of grace. How, then, can pleasure call us back to paradise, when by itself it deprived us of paradise?[49]

Origen planted the seeds for conception and birth to be “inevitably associated with a series of ‘stains,’” Brown argues, but while Origin believed these stains could be overcome with free will as the soul became ever more spiritual, Ambrose – armed with the materialistic body-soul concept of Galen filtered through the asceticism of Basil and Gregory – saw a material soul that could never rise above the scars with which it had been afflicted.[50]

The final piece

Ambrose’s emphatically severe asceticism led to an understandably negative view of marriage and its accompanying carnality. Augustine understood Ambrose as essentially leaving no room in the life of a Christian for a sexually active lifestyle, even within marriage.[51] This stringent viewpoint fit well with Augustine, whose own sexual failings had first driven him to the heretical anti-materialist dualism of the Manichaeans.[52] Cahill notes:

Not only did Augustine stand at a historical point where Christian ambivalence toward sex, and all the social roles which channeled it, was practically unavoidable, his personal experience also positioned him perfectly to reflect and magnify the tension already expressed in the Christian differentiation of celibacy and marriage.[53]

So influenced by his personal and cultural background, Augustine also brought to his discussion of sex and the soul the previously discussed set of assumptions carried forward from Galen and other Greek philosophers, through the Greek Fathers of Cappadocia and into the preaching of his mentor, Ambrose. Primary among these assumptions were the one-sex model and a materialistic view of the soul. The combination of these premises led Augustine inexorably to the notion that all of humanity was present at the creation – and therefore the fall – of Adam and Eve.

In his lengthy treatment of the nature of sin and the soul in City of God, Augustine argues humanity “was made one individual,” and that “in the first man … there existed the whole human nature, which was to be transmitted by the woman to posterity, when the conjugal union received the divine sentence of its own condemnation.” “We all were in that one man,” Augustine argued.[54] Not only this, but when woman was created through Adam’s rib, Adam was made weaker when that bone was replaced by flesh, while his bone helped strengthen the woman – thus echoing the Galenic assumption of the weaker, less perfect female.[55]

Likewise, Augustine unquestioningly repeats Ambrose’s assumptions about the necessity for male sinlessness in the conception of Christ. Citing Hebrews’ argument that Levi was in the loins of Abraham when the patriarch tithed to Melchizadek, Augustine argues all of humanity was in Adam’s loins – except Jesus, who was not conceived through male seed.[56]  Indeed, Augustine makes his assumption plain: “We must believe that even before her sin, woman had been made to be ruled by her husband.”[57] We see, then, that among the many cultural assumptions Augustine brought to the notion of sex, primary among them were two points Galen had been instrumental in articulating, and which Basil and Gregory had Christianized: The essential singularity of human gender, and the weakness of the female half of that gender.

Likewise, Augustine’s work on the nature of the soul itself reveals a familiarity and acceptance of assumptions that owe much of their provenance to the speculation of Galen three centuries earlier. For example, Augustine could just as well be discussing Galen’s pneuma when he argues “the soul does not rule its body as God does the universe,” but that “it produces breath by its motion and does not make it out of its own substance.”[58] Later, he argues the soul governs the body by means of light and air, “the two elements that have a kind of resemblance to the spirit”[59] – the kind of language that serves as a hallmark of the ancient Stoic thought that formed the backbone of Galen’s speculation on the soul.[60]

By accepting the Galenic assumption of a materialistic soul tied inextricably to the processes of the body, Augustine, after much debate, found he could embrace no alternative to the idea that the soul is created and propagated through the same process by which the body is conceived. “It is possible,” he wrote in Literal Meaning of Genesis, “that God creates both body and soul from the parents: the body from their bodies, the soul from their souls.”[61] Augustine wasn’t completely convinced at that time, as he also considered creationism, in which God creates the soul individually at the moment of conception. However, this notion left Augustine struggling with the inevitable conclusion of God’s own culpability: “We must not make God seem to be the author of sin if he gives the soul to a body in which it must necessarily sin.”[62][63] In the end, Augustine chose traducianism, citing infant baptism[64] but owing a greater debt than he seemed to realize to the intellectual legacy left by Galen: The soul simply could not be so connected to the body without being generated simultaneously with the body at the moment of conception.

With sexual intercourse playing such a central role in the creation of each individual soul, it could not help but be central to Augustine’s theological focus, as well. Although he staked out more progressive ground on sex and marriage than many of his forebears, his views on sex in general – and the physical attraction that precedes it, in particular – could not help but be negative, often strikingly so: “What friend of wisdom and holy joys, who being married … would not prefer, if this were possible, to beget children without this lust?”[65]

Even as Augustine focused on “lust” as the problem, rather than sex itself, he had difficulty keeping a strict boundary between them. “Lust requires for its consummation darkness and secrecy; and this not only when unlawful intercourse is desired, but even such fornication as the earthly city has legalized.”[66] And although Augustine argued Adam and Eve theoretically could have had sex before the fall, he believed God did not authorize it because he foreknew their eventual sin.[67] In discussing this concept, Augustine reveals a familiarity with the ideas of Basil and Gregory, as filtered through contemporaries Ambrose and Jerome. Augustine’s evocative description of the moment in which Genesis describes the first sin betrays just how central sexuality was to his view of sin and the soul: “Therefore, ‘they ate, and the eyes of both were opened.’ Opened to what except to concupiscence for one another in punishment for sin, born of the death of the flesh?”[68]

Augustine therefore made lust and untamed sexuality the primary consequences of Adam and Eve’s primal sin. When added to the conclusion that the soul is transmitted through the sex act itself, Augustine had “placed sexuality irremovably at the center of the human person,” as Brown argues.[69] The core tenets of original sin were now in place: Everyone is born with guilt from the sin in which they actively participated in the Garden of Eden, stained through the very act of intercourse that gave them life yet also transmitted the tarnished soul of Adam.[70]  This was in fact merely the natural conclusion of the philosophical legacy Augustine had inherited. The materialism with which Galen had viewed the soul and his one-body model of gender had merged almost seamlessly with a Christian ascetical reading of Genesis 1-3, thanks to the work of bishops like Basil and Gregory, who left to Augustine, through Ambrose, a theological-ascetic framework in which sexuality, sin and the soul were inextricably intertwined. When added to struggles with his own untamed sexuality, Augustine covered this framework with a doctrine that would form the basis for western Christianity’s beliefs on these subjects for centuries moving forward. Original sin is by no means a simple concept, but key tenets about the origin and transmission of the fallen human nature owe much to the philosophical underpinnings summarized first by Galen.


Proving a negative is no easy task; it does not appear Augustine knew Galen’s writings directly, though he does pause to “give some consideration to what the medical writers assert but also maintain they can prove” before launching a discussion that sounds very close to the Stoic medical tradition of which Galen was the foremost representative.[71] Nevertheless, scholars do not seem to link Augustine to Galen either directly or indirectly.

This oversight does a disservice to Galen’s influence as a philosopher and doctor. While certainly the Latin west deprived itself for many centuries of his and other Greek works, Galen’s influence was so pervasive as to be inescapable, as the experience of Augustine proves. He may never have even known the name Galen, but much of the bishop’s most transformative thinking owes a great debt to the concepts first articulated, summarized or otherwise published by the doctor, then carried through the centuries by Eastern ascetics before influencing the teaching of Augustine’s foremost mentor.

Moving forward, the influence of Augustine is difficult to overstate. Original sin remains the default position for most Christians, including the Catholic Church.[72] The bigger concern is whether that influence, especially concerning the church’s attitude toward sexuality, has been positive or negative. Augustine “created a darkened humanism that linked the pre-Christian past to the Christian present in a common distrust of sexual pleasure,” Brown writes, adding while citing Augustine’s Sermon 51: “The Christian married couple must ‘descend with a certain sadness’ to that particular task: for in the act of married intercourse itself, their very bodies spoke to them of Adam’s fall.”[73]

By tying sex closely to sin, nearly to the exclusion of all other transgressions, Augustine on the one hand perpetuated the biases of his culture and on the other confirmed and expanded them for future generations. The general Christian tendency to focus on Ps 50:7 over and against Gen 1:28, for example, can certainly be traced to the fourth-century ascetical impulse to discount sex as anything more than a biological necessity – an impulse that found its most powerful voice in the person of Augustine, with roots spreading back to Gregory and Basil, who adapted and Christianized the ideas of Galen.
