If a man fasten his attention on a single aspect of truth and apply himself to that alone for a long time, the truth becomes distorted and not itself but falsehood.
I give you joy of your free and brave thought. I have great joy in it. I find incomparable things said incomparably well, as they must be. I find the courage of treatment which so delights us, and which large perception only can inspire.
But lest I should mislead any when I have my own head and obey my whims, let me remind the reader that I am only an experimenter.Do not set the least value on what I do, or the least discredit on what I do not, as if I pretended to settle any thing as true or false. I unsettle all things. No facts are to me sacred; none are profane; I simply experiment, an endless seeker with no Past at my back.
Consider what you have in the smallest well-chosen library-a company of the wisest and wittiest men which can be plucked out of all civilized countries in a thousand years. The men themselves were then hidden and inaccessible. They were solitary, impatient of interruption, and fenced by etiquette. But now they are immortal, and the thought they did not reveal, even to their bosom friends, is here written out in transparent words of light to us, who are strangers of another age.

Broader and deeper we must write our annals, from an ethical reformation, from an influx of the ever new, ever sanative conscience, if we would trulier express our central and wide-related nature, instead of this old chronology of selfishness and pride to which we have too long lent our eyes. Already that day exists for us, shines in on us at unawares, but the path of science and of letters is not the way into nature. The idiot, the Indian, the child, and unschooled farmer's boy, stand nearer to the light by which nature is to be read, than the dissector or the antiquary.
