According to our social science, we can be or become wise in all matters of secondary importance, but we have to be resigned to utter ignorance in the most important respect: we cannot have any knowledge regarding the ultimate principles of our choices, i.e. regarding their soundness or unsoundness... We are then in the position of beings who are sane and sober when engaged in trivial business and who gamble like madmen when confronted with serious issues.

By realizing that we are ignorant of the most important things, we realize at the same time that the most important thing for us, or the one thing needful, is quest for knowledge of the most important things or quest for wisdom.

God is therefore unknowable. This is the fundamental premise of the Bible.

Liberal education, which consists in the constant intercourse with the greatest minds, is a training in the highest form of modesty. ... It is at the same time a training in boldness. ... It demands from us the boldness implied in the resolve to regard the accepted views as mere opinions, or to regard the average opinions as extreme opinions which are at least as likely to be wrong as the most strange or least popular opinions

The facile delusions which conceal from us our true situation all amount to this: that we are, or can be, wiser than the wisest men of the past. We are thus induced to play the part, not of attentive and docile listeners, but of impresarios and lion-tamers.

We somehow believe that our point of view is superior, higher than those of the greatest minds either because our point of view is that of our time, and our time, being later than the time of the greatest minds, can be presumed to be superior to their times; or else because we believe that each the greatest minds was right from his point of view, but not, as he claims, simply right.

Philosophizing means, then, to ascend from public dogma to essentially private knowledge.
