The complexities of adult life get in the way of the truth.

All genuine learning is active, not passive.

To agree without understanding is inane. To disagree without understanding is impudent.

A lecture has been well described as the process whereby the notes of the teacher become the notes of the student without passing through the mind of either.

If you are reading in order to become a better reader, you cannot read just any book or article. You will not improve as a reader if all you read are books that are well within your capacity. You must tackle books that are beyond you, or, as we have said, books that are over your head. Only books of that sort will make you stretch your mind. And unless you stretch, you will not learn.

It is love rather than sexual lust or unbridled sexuality if, in addition to the need or want involved, there is also some impulse to give pleasure to the persons thus loved and not merely to use them for our own selfish pleasure.

If one wants another only for some self-satisfaction, usually in the form of sensual pleasure, that wrong desire takes the form of lust rather than love.
