I studied Greek and Latin all my college years.
I begun reading and writing poetry...
I read extensively classics...
I begun to study mathematics and linguistics after philosophy...
Then i was less in classics and more in maths and philosophy...
I studied also mystics, astrology, psychology etc ...
I was never in one field...
Save perhaps history of consciousness through language and philosophy (Peirce, Goethe, Cassirer, Gustave Guillaume as linguist teacher )
It is why music and acoustics for me matter a lot , they are connected to this consciousness history, and the history of perception and language...
I am unable to think about a problem in one field without looking for his link to another one or to all others...
It is the only way i could created my own internal map of the history of meaning and consciousness...
For the classics i read many hundred between young age and approx 35 yearas old... I am 75...
i need books now which cost very much... Why? because i think with them...
As i said to student i hate reading.
they are stunned. And they ask me why i read all the time. I answered because the writers are geniuses i cannot afford to miss...
I dont want to read the books i never read of Melville ( Moby Dick stunned me) or read Poe another time, or read Dostoievsky or Borges whom i read young or Kafka etc...
I want to read something who is next to my thought about the cosmos. It is more about , maths, linguistics, spiritual writers now...
For a reason i will not entered here , i did not write poetry anymore...And this is what i miss the most...I read extensively poets in French some in English or German one in translation between 13 and 50 years old...Poetry is with maths and music the three most interesting fields for me.
The secrets and mysteries of human thought are hidden in these three fields..
But Natural science which i discovered with Goethe method is the deepest thinking activity with these three others...These are my interests...
A thing people dont understand is that if someone study and not only read for killing time, he search for specific books most of the times which are not in any public library....And which are too costlier to buy...
The same is true for music in a bit less costlier way...
The best version of Haydn quartet in 13 albums cost 600 Bucks...
There is only 5 on streaming apparently...
The last book that change my life was about mammal morphology : price 187 canadian bucks ...
When someone study he can look at one hundred books in a month ...
Most people buy novels... This cost nothing...
Some articles on acoustics cost 60 bucks if you dont know how to find them in another way ...
Those who dont complaint about this dont study, it is most people...
Who need Haydn? Me... but i cannot pay 600 bucks...
But happily i am very resourceful if i need a book or music...
My complaint above was not about a personal misfortune, i get all the books i want and all the music, my complaint was about the state of our social fabric where all profits goes in the same pockets and where people less resourceful cannot buy the books they need...
There is no public library in America, with the books of Lucian Blaga, Wronski, or with Mammal morphology by Wolfgang Schad for example... None...
No public library keep the works on set theory... You must be inscribed in university to borrow this ( I photocopied all my set theory books 45 years ago ) Only one book on set theory by Jech cost 192 Canadian bucks... To master set theory you must buy 50 books... Compute the price some are less costly for sure but most are costly ...And i am interested by others fields or writers than just mathematicians...
When i was young i bought 200 books of a German thinker, happily this one we can now read it free on our computer...But reading on a screen is not ideal at all ...
I can deal with it because i am old now...

Ok i will stop my rant here ...
Thanks for your patience ...

I also read extensively of science and philosophy. But if you are not reading / re-reading classic literature... I must recommend going back and reading some classics. I have gone back about three times over my life and reread most of the classics... and each time they were like new... so much more profound and deeper in meaning than I ever could have imagined when younger. I also read history...and when you put history... more or less the chronology of events and philosophy it is the literature that reflects the philosophy and events and fleshes out our past development.
I highly recommend reading / rereading: toy stories, Anna Karenina, War and Peace (really hard but the second half worth it ((listen to it)) ), Falkner’s Light in August, Henry James; The Bostonians, George Orwell’s 1984 (chronicling the current events in the US), there are hundreds more... and they don’t cost and arm and a leg.
