Hope is a good breakfast, but it is a bad supper.
Truth will sooner come out of error than from
confusion.
A prudent question is one-half of

If a man will begin with certainties,
he shall end in doubts; but if he will be content to begin with doubts he shall

experience.
If any human being earnestly desires to
push on to new discoveries instead of just retaining and using the old; to win
victories over Nature as a worker rather than over hostile critics as a
disputant; to attain, in fact, clear and demonstrative knowledge instead of
attractive and probable theory; we invite him as a true son of Science to join
our ranks.
