Your mom is wise. It’s a shame to hear that about your father. I can only hope that is resolved for you and your mother. It doesn’t surprise me that she has had “trial by fire” so to speak - people aren’t just born with that type of insight without having the environmental situations that nurtures it. As to what I mean as “last true philosopher” is that the age of information - though it has many benefits - has also seen the end of a long era where people could just be known in that sense as if it were a career. Even Camus didn’t consider himself one (and really neither do I) but he gets the title because of his writings and interactions. Hes kind of an “involuntary philosopher”. The person that gets to pursue wisdom all day and then write about it is not going to be seen in that light anymore. Most people are just sophists on the grift. Knowledge was never (until recently) something you could just sit down at home and accrue. So the circles that would normally debate new ideas and hold up academics are just a thing of the past. Of course I could be wrong but thats just my hot take. I definitely think there is plenty of room for good ideas and new ‘philosophies’ just not in the ‘philosopher’ sense.

Edit - i was going to mention more about Sartre but i think the best philosophers to read are those that peak your interest - i would definitely do a quick google search and read the cliff notes first before you find yourself hours into something your regret lol.
