“The only real science is the knowledge of how a person should live his life. And this knowledge is open to everyone.”

“Real wisdom is not the knowledge of everything, but the knowledge of which things in life are necessary, which are less necessary, and which are completely unnecessary to know. Among the most necessary knowledge is the knowledge of how to live well, that is, how to produce the least possible evil and the greatest goodness in one’s life. At present, people study useless sciences, but forget to study this, the most important knowledge.”

“Knowledge is as wings to man's life, and a ladder for his ascent. Its acquisition is incumbent upon everyone. The knowledge of such sciences, however, should be acquired as can profit the peoples of the earth, and not those which begin with words and end with words.”

“For myself, I am interested in science and in philosophy only because I want to learn something about the riddle of the world in which we live, and the riddle of man's knowledge of that world. And I believe that only a revival of interest in these riddles can save the sciences and philosophy from an obscurantist faith in the expert's special skill and in his personal knowledge and authority.”

“There is no knowledge so hard to acquire as the knowledge of how to live this life well and naturally.”

“Arts crafts and sciences uplift the world of being and are conducive to its exaltation. Knowledge is as wings to man’s life and a ladder for his ascent. Its acquisition is incumbent upon everyone.”
