An Ancient Greece philosopher, and soldier. Xenophon was much more reasonable than Socrates on pretty much every issue, and his thoughts were grounded in reality. Thankfully from Xenophon we can actually understand the realities of Ancient Greece, rather than have to rely totally on the wild ramblings of Socrates, which were plagued with hyperbole and pedophile tendencies.
