We have a hunger of the mind which asks for knowledge of all around us, and the more we gain, the more is our desire; the more we see, the more we are capable of seeing.

Do not look at stars as bright spots only. Try to take in the vastness of the universe.

There is no cosmetic for beauty like happiness.

The greatest object in educating is to give a right habit of study.

To read a book, to think it over, and to write out notes is a useful exercise; a book which will not repay some hard thought is not worth publishing.

The greatest benefit derived from the study of science is that it lifts you out of and above the littleness of daily trials. We learn to live in the universe as a part of it; we cannot seperate ourselves from it - our every act connects us with it - our every act affects the whole. Standing under the canopy of stars and remembering their presence you could scarcely do a petty deed, or think a wicked thought.

There is something of the same pleasure in noticing the hues of the stars that there is in looking at a flower garden in autumn.
