Man is the only one that knows nothing, that can learn nothing without being taught. He can neither speak nor walk nor eat, and in short he can do nothing at the prompting of nature only, but weep.

Our civilization depends largely on paper.

In comparing various authors with one another, I have discovered that some of the gravest and latest writers have transcribed, word for word, from former works, without making acknowledgment.

Human nature craves novelty.

No book so bad but some part may be of use.

Grief has limits, whereas apprehension has none. For we grieve only for what we know has happened, but we fear all that possibly may happen.

We listen with deep interest to what we hear, for to man novelty is ever charming.
