"Your classic author is the one you cannot feel indifferent to, who helps you to define yourself in relation to him, even in dispute with him."
This is the reason I choose to read classics. That quality about certain books that makes them astonishingly relatable to any situation. Classics are books that about which you can always say: "That theme can be applied to current events". Because classics hit the big themes in life, you always have a definitive opinion about them, and there is constant discussion. The books never die to the public, they are preserved for eternity. That makes them classic.
