There are temptations which strong exercise best enables us to resist

In this world we do not see things as they are. We see them as we are, because what we see depends mainly on what we are looking for.

To render ourselves insensible to pain we must forfeit also the possibilities of happiness.

The veil is slowly rising, but as regards innumerable questions we must be content to remain in ignorance.

We may sit in our library and yet be in all quarters of the earth.

Time is a trust, and for every minute of it you will have to account.

What we see depends mainly on what we look for.
