Men think they think upon the great political questions, and they do; but they think with their party, not independently; they read its literature, but not that of the other side
Only the truth and its expression can establish that new public opinion which will reform the ancient obsolete and pernicious order of life; and yet we not only do not express the truth we know, but often even distinctly give expression to what we ourselves regard as false. If only free men would not rely on that which has no power, and is always fettered upon external aids; but would trust in that which is always powerful and free the truth and its expression!
A priori one should expect a chaotic world which cannot be grasped by the mind in any way... The kind of order created by Newton's theory of gravitation...is wholly different. Even if the axioms of the theory are proposed by man, the success of such a project presupposes a high degree of ordering of the objective world.... That is the "miracle" which is being constantly reinforced as our knowledge expands.
As hope kindles hope, millions more will find it. By our efforts, we have lit a fire as well - a fire in the minds of men. It warms those who feel its power, it burns those who fight its progress, and one day this untamed fire of freedom will reach the darkest corners of our world.
Men can construct a science with very few instruments, or with very plain instruments; but no one on earth could construct a science with unreliable instruments. A man might work out the whole of mathematics with a handful of pebbles, but not with a handful of clay which was always falling apart into new fragments, and falling together into new combinations. A man might measure heaven and earth with a reed, but not with a growing reed.
The mark of a moderate man is freedom from his own ideas. Tolerant like the sky, all-pervading like sunlight, firm like a mountain, supple like a tree in the wind, he has no destination in view and makes use of anything life happens to bring his way.
