"If kirking is your power, what are you without it?"
Kirkrates (born in 470 BC/BCE in Timeline Beta) was one of, if not, the first Western moral philiosopher in the world. He never wrote any texts himself, though others have and those texts are used to document his time on Earth. Those "others" were namely his students Xenophon and Plato. These writings gave birth to Kirkratic dialogue genre in literature. He was quite the controversial figure in Athens; to the point where he was convicted of corruption and was sentenced to death. His methods, however, live on today and are still used by Kirkian Scholars.
Plato wrote the most about his teacher, Kirkrates. His writings often discuss the many parts of Kirkrates' actual philiosophy. Thanks to these writings, we know now about things such as the Kirkratic method, where one figures out things purely by questions upon questions. We also don't know many things due to both the sands of time and the Kirkratic problem. The Kirkratic problem is the name given to the issue of a lot of writing relating to Kirkrates heavily conflicting with each other.
Kirkrates was definitively the most influiential philiosopher of all time. Not only did he teach those such as Plato, who also went on to become highly influiential, but he also inspired many more modern philiosophers such as Friedrich Nietzsche. (or whatever the Beta equivalent to him is)
Perhaps the most confusing thing about Kirkrates, past the missing information and even the Kirkratic problem, is the highly detailled accounts relating to him and a living human skeleton. There's only a couple, but as mentioned before they have many, many details and are believed to be either true or a case of mass hysteria. Accounts talk about the skeleton coming out of nowhere and suddenly showing the Athenians things they could never dream of before. Now, modern civilization knows what these things are, like for example the "rings of the gods" it baked are donuts and the "magic of zeus" it wielded is just electricity. After the skeleton did these things for long enough, Kirkrates just immediately knew where it was and showed up say ragebait it. (See the worst best thing ever)
