William James William James simply asserted that his will was free. As his first act of freedom, he said, he chose to believe his will was free.

He was encouraged to do this by reading Charles Renouvier. In his diary entry of April 30,he wrote, "I think that yesterday was a crisis in my life. At any rate, I will assume for the present — until next year — that it is no illusion.

Death Over Dinner

My first act of free will shall be to believe in free will. Old-fashioned determinism was what we may call hard determinism.

It did not shrink from such words as fatality, bondage of the will, necessitation, and the like. Nowadays, we have a soft determinism which abhors harsh words, and, repudiating Essay on mind hebb, necessity, and even predetermination, says that its real name is freedom; for freedom is only necessity understood, and bondage Essay on mind hebb the highest is identical with true freedom.

James described chance as neither of these, but " indeterminism. As soon as we begin to talk indeterminism to our friends, we find a number of them shaking their heads. This notion of alternative possibilitythey say, this admission that any one of several things may come to pass is, after all, only a roundabout name for chance; and chance is something the notion of which no sane mind can for an instant tolerate in the world.


What is it, they ask, but barefaced crazy unreason, the negation of intelligibility and law? And if the slightest particle of it exists anywhere, what is to prevent the whole fabric from falling together, the stars from going out, and chaos from recommencing her topsy-turvy reign?

James was the first thinker to enunciate clearly a two-stage decision process, with chance in a present time of random alternatives, leading to a choice which grants consent to one possibility and transforms an equivocal ambiguous future into an unalterable and simple past.

It means that both Divinity Avenue and Oxford Street are called but only one, and that one either one, shall be chosen.

James was considering a case where his two choices were essentially equivalent, the so-called " liberty of indifference " the scholastic liberum arbitrium indifferentiae.

He also imagined his actions repeated in exactly the same circumstanceswhich is regarded today as one of the great challenges to libertarian free will. Imagine that I first walk through Divinity Avenue, and then imagine that the powers governing the universe annihilate ten minutes of time with all that it contained, and set me back at the door of this hall just as I was before the choice was made.

Imagine then that, everything else being the same, I now make a different choice and traverse Oxford Street. You, as passive spectators, look on and see the two alternative universes,--one of them with me walking through Divinity Avenue in it, the other with the same me walking through Oxford Street.

Now, if you are determinists you believe one of these universes to have been from eternity impossible: But looking outwardly at these universes, can you say which is the impossible and accidental one, and which the rational and necessary one?

I doubt if the most ironclad determinist among you could have the slightest glimmer of light on this point.

The History of the Free Will Problem

In other words, either universe after the fact and once there would, to our means of observation and understanding, appear just as rational as the other.

Compare James, who in suggested a strong similarity between genetic evolution and the evolution of ideas. Darwin on the other. That problem is simply this: Is the environment more likely to preserve or to destroy him, on account of this or that peculiarity with which he may be born?

But James was more willing to see accidents and chance in mental evolution. If we look at an animal or a human being, distinguished from the rest of his kind by the possession of some extraordinary peculiarity, good or bad, we shall be able to discriminate between the causes which originally produced the peculiarity in him and the causes that maintained it after it is produced; and we shall see, if the peculiarity be one that he was born with, that these two sets of causes belong to two such irrelevant cycles.

It was the triumphant originality of Darwin to see this, and to act accordingly. It might, accordingly, seem as if there were no room for any agency other than this; as if the distinction we have found so useful between "spontaneous variation," as the producer of changed forms, and the environment, as their preserver and destroyer, did not hold in the case of mental progress; as if, in a word, the parallel with Darwinism might no longer obtain But, in spite of all these facts, I have no hesitation whatever in holding firm to the Darwinian distinction even here.

I maintain that the facts in question are all drawn from the lower strata of the mind, so to speak, - from the sphere of its least evolved functions, from the region of intelligence which man possesses in common with the brutes.

James sounds much like Lucretius in his descriptions of random images that "come to us. It is one of the tritest truisms that human intelligences of a simple order are very literal. They are slaves of habit, doing what they have been taught without variation; dry, prosaic, and matter-of-fact in their remarks; devoid of humor, except of the coarse physical kind which rejoices in a practical joke; taking the world for granted; and possessing in their faithfulness and honesty the single gift by which they are sometimes able to warm us into of Hebb's book on the occasion of the 50th anniversary (Sejnowski, ) and this essay gives me the opportunity to put recent discoveries in synap-.
