Curiosity is its own suicide.

We might have been - these are but common words, and yet they make the sum of life's bewailing.

Toil is the portion of day, as sleep is that of night; but if there be one hour of the twenty-four which has the life of day without its labor, and the rest of night without its slumber, it is the lovely and languid hour of twilight.

The very effort to forget teaches us to remember.

Enthusiasm is the divine particle in our composition: with it we are great, generous, and true; without it, we are little, false, and mean.

Knowledge is much like dust - it sticks to one, one does not know how.

My heart is its own grave!
