Nature would not appear so rich, the profusion so rich, if we knew a use for everything.

Nature and human life are as various as our several constitutions. Who shall say what prospect life offers to another?

How we shall earn our bread is a grave question; yet it is a sweet and inviting question. Let us not shirk it, as is usually done.It is the most important and practical question which is put to man. Let us not answer it hastily. Let us not be content to get our bread in some gross, careless, and hasty manner. Some men go a-hunting, some a-fishing, some a-gaming, some to war; but none have so pleasant a time as they who in earnest seek to earn their bread.

No doubt Carlyle has a propensity to exaggerate the heroic in history, that is, he creates you an ideal hero rather than another thing.... Yet what were history if he did not exaggerate it? How comes it that history never has to wait for facts, but for a man to write it? The ages may go on forgetting the facts never so long, he can remember two for every one forgotten. The musty records of history, like the catacombs, contain the perishable remains, but only in the breast of genius are embalmed the souls of heroes.

The better part of the man is soon ploughed into the soil for compost. By a seeming fate, commonly called necessity, they are employed, as it says in an old book, laying up treasures which moth and rust will corrupt and thieves break through and steal. It is a fool's life, as they will find when they get to the end of it, if not before.

The Indian navigator naturally distinguishes by a name those parts of a stream where he has encountered quick water and forks, andagain, the lakes and smooth water where he can rest his weary arms, since those are the most interesting and more arable parts to him.

He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one. Mathematics should be mixed not only with physics but with ethics; that is mixed mathematics. The fact which interests us most is the life of the naturalist. The purest science is still biographical.
