Page 51 - The end of our foundation is the knowledge of causes, and secret motions of things; and the enlarging of the bounds of human empire, to the effecting of all things possible.
Page 511 - ... the passage from the current to the needle, if not demonstrable, is thinkable, and that we entertain no doubt as to the final mechanical solution of the problem. But the passage from the physics of the brain to the corresponding facts of consciousness is unthinkable. Granted that a definite thought, and a definite molecular action in the brain occur simultaneously ; we do not possess the intellectual organ, nor apparently any rudiment of the organ, which would enable us to pass, by a process...

Page 54 - To sit on rocks, to muse o'er flood and fell, To slowly trace the forest's shady scene, Where things that own not man's dominion dwell, And mortal foot hath ne'er or rarely been ; To climb the trackless mountain all unseen, With the wild flock that never needs a fold; Alone o'er steeps and foaming falls to lean ; This is not solitude; 'tis but to hold Converse with Nature's charms, and...
Page 511 - In affirming that the growth of the body is mechanical, and that thought, as exercised by us, has its correlative in the physics of the brain, I think the position of the " Materialist " is stated, as far as that position is a tenable one. I think the materialist will be able finally to maintain this position against all attacks; but I do not think, in the present condition of the human mind, that he can pass beyond this position.
