“Speech is for the convenience of those who are hard of hearing; but there are many fine things which we cannot say if we have to shout.”

“There are many fine things we cannot say if we have to shout.”

“A man receives only what he is ready to receive, whether physically or intellectually or morally, as animals conceive at certain seasons their kind only. We hear and apprehend only what we already half know. If there is something which does not concern me, which is out of my line, which by experience or by genius my attention is not drawn to, however novel and remarkable it may be, if it is spoken, we hear it not, if it is written, we read it not, or if we read it, it does not detain us. Every man thus tracks himself through life, in all his hearing and reading and observation and traveling. His observations make a chain. The phenomenon or fact that cannot in any wise be linked with the rest which he has observed, he does not observe. By and by we may be ready to receive what we cannot receive now. I find, for example, in Aristotle some thing about the spawning, etc., of the pout and perch, because I know something about it already and have my attention aroused; but I do not discover till very late that he has made other equally important observations on the spawning of other fishes, because I am not interested in those fishes.”

“We cannot see anything until we are possessed with the idea of it, take it into our heads, - and then we can hardly see anything else.”

“Most men appear never to have considered what a house is, and are actually though needlessly poor all their lives because they think that they must have such a one as their neighbors have. As if one were to wear any sort of coat which the tailor might cut out for him, or gradually leaving off palm-leaf hat or cap of woodchuck skin, complain of hard times because he could not afford to buy him a crown! It is possible to invent a house still more convenient and luxurious than we have, which yet all would admit that man could not afford to pay for. Shall we always study to obtain more of these things, and not sometimes be content with less?”

“Let us... work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance, that alluvion which covers the globe...till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake... ”

“What demon possessed me that I behaved so well? You may say the wisest thing you can old man, — you who have lived seventy years, not without honor of a kind,– I hear an irresistible voice which invites me away from all that.”
