“Roads are a record of those who have gone before.”

The Inferno (1917), Ch. XIV
Context: I thought of all those wise men, poets, artists before me who had suffered, wept, and smiled on the road to truth. I thought of the Latin poet who wished to reassure and console men by showing them truth as unveiled as a statue. A fragment of his prelude came to my mind, learned long ago, then dismissed and lost like almost everything that I had taken the pains to learn up till then. He said he kept watch in the serene nights to find the words, the poem in which to convey to men the ideas that would deliver them. For two thousand years men have always had to be reassured and consoled. For two thousand years I have had to be delivered. Nothing has changed the surface of things. The teachings of Christ have not changed the surface of things, and would not even if men had not ruined His teachings so that they can no longer follow them honestly. Will the great poet come who shall settle the boundaries of belief and render it eternal, the poet who will be, not a fool, not an ignorant orator, but a wise man, the great inexorable poet? I do not know, although the lofty words of the man who died in the boarding-house have given me a vague hope of his coming and the right to adore him already.

Context: Don't keep forever on the public road, going only where others have gone. Leave the beaten track behind occasionally and dive into the woods. You will be certain to find something you have never seen before, and something worth thinking about to occupy your mind. All really big discoveries are the result of thought.

Context: There are those in this country who threaten direct action to force their will, upon a majority. Russia today, with its blood and terror, is a painful object lesson of the power of minorities. It makes little difference what minority it is; whether capital or labor, or any other class; no sort of privilege will ever be permitted to dominate this country. We are a partnership or nothing that is worth while. We are a democracy, where the majority are the masters, or all the hopes and purposes of the men who founded this government have been defeated and forgotten. In America there is but one way by which great reforms can be accomplished and the relief sought by classes obtained, and that is through the orderly processes of representative government. Those who would propose any other method of reform are enemies of this country. America will not be daunted by threats nor lose her composure or calmness in these distressing times. We can afford, in the midst of this day of passion and unrest, to be self - contained and sure. The instrument of all reform in America is the ballot. The road to economic and social reform in America is the straight road of justice to all classes and conditions of men. Men have but to follow this road to realize the full fruition of their objects and purposes. Let those beware who would take the shorter road of disorder and revolution. The right road is the road of justice and orderly process.

Context: The ultimate objective test of free will would seem to be: Can one predict the behavior of the organism? If one can, then it clearly doesn't have free will but is predetermined. On the other hand, if one cannot predict the behavior, one could take that as an operational definition that the organism has free will … The real reason why we cannot predict human behavior is that it is just too difficult. We already know the basic physical laws that govern the activity of the brain, and they are comparatively simple. But it is just too hard to solve the equations when there are more than a few particles involved … So although we know the fundamental equations that govern the brain, we are quite unable to use them to predict human behavior. This situation arises in science whenever we deal with the macroscopic system, because the number of particles is always too large for there to be any chance of solving the fundamental equations. What we do instead is use effective theories. These are approximations in which the very large number of particles are replaced by a few quantities. An example is fluid mechanics … I want to suggest that the concept of free will and moral responsibility for our actions are really an effective theory in the sense of fluid mechanics. It may be that everything we do is determined by some grand unified theory. If that theory has determined that we shall die by hanging, then we shall not drown. But you would have to be awfully sure that you were destined for the gallows to put to sea in a small boat during a storm. I have noticed that even people who claim everything is predetermined and that we can do nothing to change it, look before they cross the road. … One cannot base one's conduct on the idea that everything is determined, because one does not know what has been determined. Instead, one has to adopt the effective theory that one has free will and that one is responsible for one's actions. This theory is not very good at predicting human behavior, but we adopt it because there is no chance of solving the equations arising from the fundamental laws. There is also a Darwinian reason that we believe in free will: A society in which the individual feels responsible for his or her actions is more likely to work together and survive to spread its values.
