All I have learned, I learned from books.

Self-education is, I firmly believe, the only kind of education there is.

I read my eyes out and can't read half enough...the more one reads the more one sees we have to read.

Great books make great being.

All the world is my school and all humanity is my teacher.

Upon the subject of education, not presuming to dictate any plan or system respecting it, I can only say that I view it as the most important subject which we as a people can be engaged in.
