Human Nature and Conduct by John Dewey — Read

Since morals is concerned with conduct, it grows out of specific empirical facts. Almost all influential moral theories, with the exception of the utilitarian, have refused to admit this idea. For Christendom as a whole, morality has been connected with supernatural commands, rewards and penalties. Those who have escaped this superstition have contented themselves with converting the difference between this world and the next into a distinction between the actual and the ideal, what is and what should be. The actual world has not been surrendered to the devil in name, but it is treated as a display of physical forces incapable of generating moral values. Consequently, moral considerations must be introduced from above. Human nature may not be officially declared to be infected because of some aboriginal sin, but it is said to be sensuous, impulsive, subjected to necessity, while natural intelligence is such that it cannot rise above a reckoning of private expediency.

But in fact morals is the most humane of all subjects. It is that which is closest to human nature; it is ineradicably empirical, not theological nor metaphysical nor mathematical. Since it directly concerns human nature, everything that can be known of the human mind and body in physiology, medicine, anthropology, and psychology is pertinent to moral inquiry. Human nature exists and operates in an environment. And it is not "in" that environment as coins are in a box, but as a plant is in the sunlight and soil. It is of them, continuous with their energies, dependent upon their support, capable of increase only as it utilizes them, and as it gradually rebuilds from their crude indifference an environment genially civilized. Hence physics, chemistry, history, statistics, engineering science, are a part of disciplined moral knowledge so far as they enable us to understand the conditions and agencies through which man lives, and on account of which he forms and executes his plans. Moral science is not something with a separate province. It is physical, biological and historic knowledge placed in a human context where it will illuminate and guide the activities of men.
