It is "natural" for activity to be agreeable. It tends to find fulfilment, and finding an outlet is itself satisfactory, for it marks partial accomplishment. If productive activity has become so inherently unsatisfactory that men have to be artificially induced to engage in it, this fact is ample proof that the conditions under which work is carried on balk the complex of activities instead of promoting them, irritate and frustrate natural tendencies instead of carrying them forward to fruition. Work then becomes labor, the consequence of some aboriginal curse which forces man to do what he would not do if he could help it, the outcome of some original sin which excluded man from a paradise in which desire was satisfied without industry, compelling him to pay for the means of livelihood with the sweat of his brow. From which it follows naturally that Paradise Regained means the accumulation of investments such that a man can live upon their return without labor. There is, we repeat, too much truth in this picture. But it is not a truth concerning original human nature and activity. It concerns the form human impulses have taken under the influence of a specific social environment. If there are difficulties in the way of social alteration--as there certainly are--they do not lie in an original aversion of human nature to serviceable action, but in the historic conditions which have differentiated the work of the laborer for wage from that of the artist, adventurer, sportsman, soldier, administrator and speculator. IV War and the existing economic regime have not been discussed primarily on their own account. They are crucial cases of the relation existing between original impulse and acquired habit. They are so fraught with evil consequences that any one who is disposed can heap up criticisms without end. Nevertheless they persist. This persistence constitutes the case for the conservative who argues that such institutions are rooted in an unalterable human nature. A truer psychology locates the difficulty elsewhere. It shows that the trouble lies in the inertness of established habit. No matter how accidental and irrational the circumstances of its origin, no matter how different the conditions which now exist to those under which the habit was formed, the latter persists until the environment obstinately rejects it. Habits once formed perpetuate themselves, by acting unremittingly upon the native stock of activities. They stimulate, inhibit, intensify, weaken, select, concentrate and organize the latter into their own likeness. They create out of the formless void of impulses a world made in their own image. Man is a creature of habit, not of reason nor yet of instinct.
