So far this is mere impiety, but now matters take a new turn. ‘I think that we two are of one religion,’ Medicus says, conspiratorially. Antonius is nonplussed: ‘I know not mine own religion’, so how can it be the same as someone else’s? Medicus now asks him to check that no one else can overhear them: secrets are about to be spoken. When he is certain that they are alone, he says to Antonius: ‘Hark in your ear sir, I am neither Catholic, Papist, Protestant, nor Anabaptist.’ Antonius asks, ‘What do you honour? The sun, the moon, or the stars?’ None of them, says Medicus. ‘To be plain, I am a Nulla fidian’: a person of no faith. (The newly coined English word atheist was not yet in widespread use.) ‘There are many of our sect’, he adds. And then comes the truly remarkable feature of this exchange. Having heard what ought to be the most shocking religious confession imaginable, Antonius is almost disappointed. He had apparently been hoping for something more novel. ‘Oh. One who says in his heart there is no God. Well, we differ very little in this point.’ He takes his prescription and leaves Medicus to his next patient.[33]
This was satirical fiction, the work of an author who was himself an ardent believer, and ought not to be taken too literally. Still, this much is plain. Physicians were the heirs to medieval Europe’s most robustly secular intellectual tradition. And while they might accept God’s role in human health and sickness, they could do nothing about it and so inevitably tended to ignore it. Whatever their own beliefs, their vocation led them to neglect God, and to do so at a moment when a patient might otherwise be rediscovering the urgency of faith.
So the physician’s consulting room can join the alehouse and gaming table on our list of secularised spaces. Since learned medicine was a tiny world, the preserve of a handful of university-educated doctors and those wealthy enough to be able to afford their services, this is perhaps not very important. Moreover, for all medieval and early modern medicine’s self-importance, it was very often useless and frequently worse, which did not increase its moral authority. Even the staunchest atheist might have been wiser to trust in God’s mercy than to submit to a medieval physician.
Nevertheless, medical secularism could be corrosive, for even in the Middle Ages medicine always held the potential for innovation and scepticism. Patients had an irritating tendency to be more interested in whether a treatment worked than in whether it had good scholarly credentials. When the medical establishment despised experimenters as ‘empirics’ and froze them out of the academy, this merely spurred them on. It is no coincidence that the most notorious Christian dissident of the sixteenth century, Miguel Servetus, who denied the doctrines of the Trinity and of original sin, was also a physician who pioneered theories of the circulation of blood. In the following century, Sir Thomas Browne peered over the edge of unbelief with a coolly critical eye, and used his professional skills to ask searching questions of his religion. The method for determining virginity provided in the book of Deuteronomy, ‘I find … is very fallible’. He suggested that the supposed miracle by which Moses defended the Israelites from snakebite was ‘but an Egyptian trick’; that the fire Elijah had called down from Heaven could be explained chemically; that the destruction of Sodom and Gomorrah was due to ‘Asphaltic and Bituminous’ materials in the water rather than to the people’s sin. This kind of thinking was by no means a slippery slope to atheism – Browne’s case proves that, as we will see – but nor was it a path to simple faith.[34]
In the late 1650s, a Parisian priest named Paul Beurrier visited an aged physician in his parish, whose name he gave only as Basin. This man had travelled widely in Europe, in Turkey and in the East Indies, and had studied with Protestants, Jews, Muslims and Indian Brahmins. In the end, he concluded that ‘all religions were only dreams, and political institutions used by rulers to use the deception of religion and the fear of Divinity to procure their subjects’ submission’. He returned to Paris, ‘determined to live and to die in philosophy’. Beurrier, the kind of priest who enjoys a challenge, visited Basin several times, and Basin eventually laid out for him what he called ‘my philosopher’s religion’. He accepted the existence of a distant, impersonal God who ‘did not involve himself in our affairs, as being beneath him’, but he insisted: ‘First, that the Christian religion is the greatest of all fables; second, that the Bible is the oldest of all fictions; third, that the greatest of all deceivers and impostors is Jesus Christ.’
Basin’s profession was no incidental part of his identity. Early in their acquaintance, Beurrier remarked platitudinously that Basin surely wished to live and die a good Christian. Basin indignantly denied it: ‘I am a physician and philosopher. I have no other religion than to be a philosopher, and wish to die a philosopher, as I have lived.’
Basin is not the only shockingly frank character in Beurrier’s memoirs, and the story seems to have lost nothing in the telling.[35] But with its suggestion that Christian and physician were incompatible alternatives, it implies that the medical world was one of those reservoirs in which unbelief lay dormant throughout the Middle Ages – until stirred into life by what Basin called ‘philosophy’. That brings us out of this medical byway into the cultural upheaval that defined the modern age.
From Ancient to Modern
Medieval Europe was Christian to its bones; but it also venerated the ancient world, which had only latterly embraced Christianity, and some of whose greatest minds had rejected religion of any kind. Medieval theology’s central scholarly project was to reconcile the Christian and Graeco-Roman intellectual legacies. In its own terms, this project was impressively successful, but no sooner was the battle won in the thirteenth century than an unexpected new front opened up. The brash new movement that arose in the city-states of northern Italy was not trying to cause religious trouble. This ‘Renaissance’, as we now call it, was a cultural and a political project. A series of scrappy, turbulent and remarkably wealthy miniature republics were trying to stabilise themselves and to protect their independence from one another, and from the twin threats of the papacy to the south and the Holy Roman Empire to the north.
In an era when hereditary monarchy was the norm, republican city-states were a novelty, but there was an obvious precedent: the pagan republics of ancient Greece and Rome. Italians who studied those examples quickly found that their political lifeblood had been oratory, rhetoric and the art of persuasion. So what we call the Renaissance began as an attempt to recover the eloquence of the age of Cicero, to scale once again the heights of Latin as it had been used in the classical era, in order to rebuild Rome’s glories in Florence, Pisa and Siena.
These pioneers of the Renaissance venerated the ancient world at least as much as any other medieval scholars, but they used that veneration in a new way. Instead of humbly seeing themselves as heirs of an unbroken tradition, charged with preserving, transmitting and (perhaps, cautiously) interpreting it, they came to suspect that during the long ages separating themselves from the ancients, corruptions had crept in. The everyday Latin of the medieval Church and university seemed barbarous and uncouth next to
