The Senate struck down the “don’t ask, don’t tell” policy, allowing gays to serve openly in the military. Unlike gay marriage, this is not unprecedented. In fact, the Greeks sometimes purposefully cultivated homosexual attachments in military units in order to build unit cohesion. This happened among the Spartans. The most famous example, though, was the elite fighting force known as the Theban Band, a.k.a., the Sacred Band of Thebes:
Plutarch records that the Sacred Band was made up of male couples, the rationale being that lovers could fight more fiercely and cohesively than strangers with no ardent bonds. According to Plutarch’s Life of Pelopidas, the inspiration for the Band’s formation came from Plato’s Symposium, wherein the character Phaedrus remarks,
“And if there were only some way of contriving that a state or an army should be made up of lovers and their beloved, they would be the very best governors of their own city, abstaining from all dishonour, and emulating one another in honour; and when fighting at each other’s side, although a mere handful, they would overcome the world. For what lover would not choose rather to be seen by all mankind than by his beloved, either when abandoning his post or throwing away his arms? He would be ready to die a thousand deaths rather than endure this. Or who would desert his beloved or fail him in the hour of danger?”
The Sacred Band originally was formed of hand-picked men who were couples, each lover and beloved selected from the ranks of the existing Theban citizen-army. The pairs consisted of the older “heníochoi”, or charioteers, and the younger “parabátai”, or companions, all housed and trained at the city’s expense in order to fight as hoplites. During their early engagements, they were dispersed by Gorgidas throughout the front ranks of the Theban army in an attempt to bolster morale.
This, of course, is not the kind of unit cohesion our forces try to cultivate today. The soldiers in these arrangements would live in homosexual relationships during their military commitment, but then afterwards they would usually get married and live normal heterosexual lives.
There is apparently a cultural component, at least in some cases, to homosexual behavior. I’m not denying that some people seem to have some sort of innate same-sex attraction. Still, it might help to study homosexuality in the ancient world, which was rampant–contrary to those who think the Biblical authors did not know anything about the subject–and yet it was also fluid–contrary to those who insist that homosexuality is always a fixed condition–with people going back and forth from homosexuality and heterosexuality.
