Pliny the Elder

Nature is to be found in her entirety nowhere more than in her smallest creatures.

Home is where the heart is.

How many things, too, are looked upon as quite impossible until they have been actually effected?

Man is the only animal that knows nothing and can learn nothing without being taught.

It is far from easy to determine whether Nature has proved to man a kind parent or a merciless stepmother.

An object in possession seldom retains the same charm that it had in pursuit.

The only certainty is that nothing is certain.

True glory consists in doing what deserves to be written, in writing what deserves to be read, and in so living as to make the world happier for our living in it.

The depth of darkness to which you can descend and still live is an exact measure of the height to which you can aspire to reach.
