Science is a first-rate piece of furniture for a man's upper chamber, if he has common sense on the ground floor. - Oliver Wendell Holmes

Call him not old whose visionary brain Holds o’er the post its undivided reign, For him in vain the envious seasons roll, Who bears eternal summer in this soul.

Wake in our breast the living fires,
The holy faith that warmed our sires;
Thy hand hath made our nation free;
To die for her is serving Thee.

I say that conceit is just as natural a thing to human minds as a centre is to a circle. But little-minded people's thoughts move in such small circles that five minutes' conversation gives you an arc long enough to determine their whole curve. An arc in the movement of a large intellect does not sensibly differ from a straight line. Even if it have the third vowel ['I', the first-person pronoun] as its centre, it does not soon betray it. The highest thought, that is, is the most seemingly impersonal; it does not obviously imply any individual centre.
