What is a philosopher? They are not ‘categories’ just examples of how the term can be, and is, used. A ‘philosophy of life’ is colloquial whilst scholarship is technical by nature.
I hear this kind of thinking from people who are just too lazy to put the work in tbh. You might be different. I just don’t think it makes any sense for anyone to label themselves as a ‘philosopher’ if they have never actually read ( and I mean REALLY read) an actual work of philosophy.
Note: Lots of people don’t know how to read, they just ‘read the words’ and think they have read and understood something. Sadly it is skill most people don’t develop much beyond teenage years - if that!
Too many people out there (including myself) here some brief excerpt from a philosopher and think themselves enlightened because ‘we thought/knew that already’.
I don’t regard people who have been to university to study philosophy as ‘philosophers’ though. Just stating it is pretty damn silly to paint yourself as something without having partook in some rigorous and active sense with what is already there.
Stoicism is like electronics is to physics. Someone can specialise in electronics and know very little about cosmology … I have no idea where any line of distinction could be between specialist subjects and a more broader overview? I probably would not approach a stoic to get feedback about most epistemic issues as I have a fairly decent suspicion that the discussion would lead into ethical realms and that might not be of focus for me.
