You must not talk about 'ain't and can't' when you speak of this great wonderful world round you, of which the wisest man knows only the very smallest corner, and is, as the great Sir Isaac Newton said, only a child picking up pebbles on the shore of a boundless ocean.

If you wish to be like a little child, study what a little child could understand — nature; and do what a little child could do — love.

Do today's duty, fight to-day's temptation; and do not weaken and distract yourself by looking forward to things which you cannot see, and could not understand if you saw them.

Better is old wine than new, and old friends like-wise.

I can conceive few human states more enviable than that of the man to whom, panting in the foul laboratory, or watching for his life under the tropic forest, Isis shall for a moment lift her sacred veil, and show him, once and for ever, the thing he dreamed not of; some law, or even mere hint of a law, explaining one fact; but explaining with it a thousand more, connecting them all with each other and with the mighty whole, till order and meaning shoots through some old Chaos of scattered observations.

Music. – There is something very wonderful in music. Words are wonderful enough: but music is even more wonderful. It speaks not to our thoughts as words do: it speaks straight to our hearts and spirits, to the very core and root of our souls. Music soothes us, stirs us up; it puts noble feelings into us; it melts us to tears, we know not how: – it is a language by itself, just as perfect, in its way, as speech, as words; just as divine, just as blessed.

We ought to reverence books; to look on them as useful and mighty things. If they are good and true, whether they are about religion, politics, farming, trade, law, or medicine, they are the message of Christ, the maker of all things - the teacher of all truth.
