Recently a friend remarked to me that there was one superstition current among even cultivated persons. They suppose that if one is told what to do, if the right _end_ is pointed to them, all that is required in order to bring about the right act is will or wish on the part of the one who is to act. He used as an illustration the matter of physical posture; the assumption is that if a man is told to stand up straight, all that is further needed is wish and effort on his part, and the deed is done. He pointed out that this belief is on a par with primitive magic in its neglect of attention to the means which are involved in reaching an end. And he went on to say that the prevalence of this belief, starting with false notions about the control of the body and extending to control of mind and character, is the greatest bar to intelligent social progress. It bars the way because it makes us neglect intelligent inquiry to discover the means which will produce a desired result, and intelligent invention to procure the means. In short, it leaves out the importance of intelligently controlled habit. We may cite his illustration of the real nature of a physical aim or order and its execution in its contrast with the current false notion.[1] A man who has a bad habitual posture tells himself, or is told, to stand up straight. If he is interested and responds, he braces himself, goes through certain movements, and it is assumed that the desired result is substantially attained; and that the position is retained at least as long as the man keeps the idea or order in his mind. Consider the assumptions which are here made. It is implied that the means or effective conditions of the realization of a purpose exist independently of established habit and even that they may be set in motion in opposition to habit. It is assumed that means are there, so that the failure to stand erect is wholly a matter of failure of purpose and desire. It needs paralysis or a broken leg or some other equally gross phenomenon to make us appreciate the importance of objective conditions. [1] I refer to Alexander, "Man's Supreme Inheritance."
