Great post! One of my main interests in the steemit community is the platform which I think it provides for philosophy; sort of the ultimate modern day square of Athens! I studied philosophy in college and grew disillusioned in the end because of I felt it became more about the dogma of "who said what" than anything else.

I think we generally use the term philosopher to define someone who is able to make a living out of the study of philosophy, however personally, I would say that a philosopher is anybody that asks and contemplates the larger questions there are in life and discusses it with others. 

Really anybody who pursues knowledge, in whatever field, is a sort of philosopher (hence the use of PHD 'Doctor of Philosophy' in all different subjects). While that may seem sort of silly now, the advancements of the sciences really developed from the very philosophical questions of why and how.
