What are the chief disharmonies? I mean, of course, glaring disharmonies, for no one is of harmonious development, with intelligence, emotions, instincts, desires, purposes in cooperation with each other. This I propose to consider in more detail in the next chapter, on some character types, but it will be of use to sketch the great disharmonies. Character is dynamic, and a fundamental disharmony, even if not noticeable early in life, may progress to the point of disruption of the personality. Thus an individual who is strongly egoistic in his purposes and aims may succeed if at the same time he is determined intelligent and shrewd. But let us suppose he has a son who is as strongly egoistic, is as determined, but lacks intelligence and shrewdness. Not becoming successful, this person ascribes his failure to others and develops ideas of persecution. Again, a true poet is a person of keen sensibilities, but he must possess at the same time imaginative intelligence and the power of words. Let these be joined in proper proportions, and his verse becomes ours and we hail him as a poet. But let him lack the power of words, and though he sweat with a desire to write he is a failure or a hack poet, making up by industry what he lacks in beauty. Suppose there is a man deeply passionate, thrilled by the beauty of women and desiring them with a fierce ardor, and yet he has strong inhibitions, great purposes which hold him steady. Then throughout life he seems calm, chaste and controlled, and no one knows of the turmoil and battle within him. We may suppose that old age[1] or a sickness lowers his inhibiting qualities, and a startling change in conduct results, one that we can scarcely believe and which we are inclined to call a complete transformation of personality. In reality, a disharmony has occurred, some trend has been released, and conduct, which is a resultant, changes its direction. [1] Sexual misdemeanor is not uncommon in old men who have hitherto been of hallowed reputation.
