them when opportunity offered, a still larger percentage of my practice would be lost."
The undoubted fact that our own acts do not cause in us the same emotions as similar acts on the part of others is one of the strangest psychological truths. This legacy from unevolved man, from the times when brute might was the only right, has been handed down to us. This legacy is still a beam of varying size in every human eye. We shall probably long continue to excuse certain acts of our own and of our friends and to criticise our enemies severely for those same deeds. We see this tendency full-fledged in animals. A big, strong dog will take away a bone from a starving dog. A wealthy railroad president and wealthy directors will plan to wreck a rival road whose bonds and stock may constitute a large proportion of the investments of some orphans. These men would experience intense emotion if any one attempted to steal from a child of theirs. They will steal from the children of others without a qualm. The advance in intelligence has many times served to increase this tendency. Napoleon was a very intelligent man. The promoters of hydra-headed trusts are men of great sagacity. It is nevertheless true that, as a man acquires the habit of reflecting on his own actions, as he by an effort places himself in a neutral position, and from that changed point of view looks at his deeds with another's eyes, as he puts himself in the place of those whom his acts have inconvenienced or wronged, this brute legacy, so destructive of truth, will grow less and less. But only the possessor of a vivid imagination, either natural or acquired, can ever succeed in doing this. Children who are early taught to regard each act from the point of view of those affected by that act are placed in the royal road to overcome this tendency. A successful business man recently said that he did not wish his children thus taught, for such training would put them at a disadvantage in the struggle for existence.
True conceptions are hampered not only by those emotions which are popularly termed peculiarly egoistic, but by all emotion, which a searching investigation shows to rest upon a hidden foundation sunk deep in those feelings which affect the self for weal or woe. All emotion has a twofold aspect in regard to thought and the search for truth. On the one hand, emotion supplies all the interest we feel in any subject, and is thus absolutely necessary for all long-continued, earnest thought; on the other hand, there is thus a deflecting power necessarily at work in the center of every thought. The strong desire to prove a certain theory has led the most honest of men to look at certain facts through colored glasses. It is often dangerous to consult any medical specialist at first, because he will have a tendency to see unmistakable signs of the complaint which he treats. Only those
