Faith in the possibilities of continued and rigorous inquiry does not limit access to truth to any channel or scheme of things. It does not first say… - John Dewey

When the organization called soul is free, moving and operative, initial as well as terminal, it is spirit. Qualities are both static, substantial, and transitive. Spirit quickens; it is not only alive, but spirit gives life. Animals are spirited, but man is a living spirit. He lives in his works and his works do follow him. Soul is form, spirit informs. It is the moving function of that of which soul is the substance. Perhaps the words soul and spirit are so heavily laden with traditional mythology and sophisticated doctrine that they must be surrendered; it may be impossible to recover for them in science and philosophy the realities designated in idiomatic speech. But the realities are there, by whatever names they be called.

Classical science was based upon the belief that it is possible to formulate both the position and velocity at one time of any given particle. It followed that knowledge of the position and velocity of a given number of particles would enable the future behavior of the whole collection to be accurately predicted. The principle of Heisenberg is that given the determination of position, its velocity can be stated only as of a certain order of probability, while if its velocity is determined the correlative factor of position can be stated only as of a certain order of probability. Both cannot be determined at once, from which it follows necessarily that the future of the whole collection cannot possibly be foretold except in terms of some order of probability.

It is mere ignorance that leads then to the supposition that connection of art and esthetic perception with experience signifies a lowering of their significance and dignity.
