It is the empiric who never fails.

The gloomy recess of an ecclesiastical library is like a harbor, into which a far-traveling curiosity has sailed with its freight, and cast anchor. The ponderous tomes are bales of the mind's merchandise. Odors of distant countries and times steal from the red leaves, the swelling ridges of vellum, and the titles in tarnished gold.

Newton found that a star, examined through a glass tarnished by smoke, was diminished into a speck of light. But no smoke ever breathed so thick a mist as envy or detraction.

Poetical taste is the only magician whose wand is not broken. No hand, except its own, can dissolve the fabric of beauty in which it dwells. Genii, unknown to Arabian fable, wait at the portal. Whatever is most precious from the loom or the mine of fancy is poured at its feet. Love, purified by contemplation, visits and cheers it; unseen musicians are heard in the dark; it is Psyche in the palace of Cupid.

The history of men of science has one peculiar advantage, as it shows the importance of little things in producing great results. Smeaton learned his principle of constructing a lighthouse, by noticing the trunk of a tree to be diminished from a curve to a cyclinder ... and Newton, turning an old box into a water-clock, or the yard of a house into a sundial, are examples of those habits of patient observation which scientific biography attractively recommends.

It is only dislocated minds whose movements are spasmodic.

Genius is nourished from within and without.
