When a person (especially a person of younger age) read a piece of philosophy by a great philosopher, be it Socrates or Sartre, very often he cannot make a proper judgment by himself, because although he has good command of logic, he lacks experience about the world which is fundamental in making his own evaluation. And the inequality of intellectual maturity between him and the philosopher makes things worse. The philosopher he read maybe received a much better education than him, that philosopher may speak more than two foreign languages and have a life time of experience, therefore very often all he can do is to accept the paradigm of that philosopher.
For example, when I read important philosophers like Schopenhauer, a person who lived two hundred years ago yet writes with so much greater clarity, lucidness and genius than those self-claimed philosophers of our time, I cannot resist but to go along with his train of thoughts.
Schopenhaur once said: “… you may look upon life as an unprofitable episodes, disturbing the blessed calm of non-existence. And, in any case, even though things have gone with you tolerably well, the longer you live the more clearly you will feel that, on the whole, life is a disappointment, nay, a cheat.”
And when I read the quote by him above, I cannot make my own evaluation, If I want to evaluate it, I have to ask a 80 years old person " Do you think life is a cheat or not?"
I suspect a young person can never make an objective evaluation after reading philosophy like this, because if that young man/woman believe Schopenhaur is right after reading it, then that young person will see his/her later life as an evidence, or a footnote to Schopenhaur philosophy, that life is a cheat.
Schopenhaur once talked about the danger of reading/studying.
A professor once told me :" Although I’m a philosophy professor, I have to be honest with you, Studying philosophy when one is young is really not a good thing, because when an inexperienced young man study philosophy, all he can get is a mind full of empty concepts spinning around. He has no foundation— the experience of life, to base his thinking, therefore don’t study philosophy until you turn 30." Maybe he is right, all that young man can be is a book-philosopher.
After all, Is reading/studying philosophy beneficial for a young person?
