Therefore it is of _great_ importance for all people who take up and pursue to any degree of success this Art or Science, that they shall be actuated by moral and unselfish motives, since achieved with any other intent the end can only be the bringing of evil and suffering into the soul. For as the good by strengthening the Will make themselves promptly better and holier, so he who increases it merely to make others feel his power will become with it wickeder, yea, and thrice accursed, for what is the greatest remedy is often the strongest poison. Step by step Science has advanced of late to the declaration that man _thinks all over_ his body, or at least experiences those reflected sensations or emotions which are so strangely balanced between intellectual sense and sensation that we hardly know where or how to class them. "The sensitive _plexi_ of our whole organism are all either isolated or thrown into simultaneous vibration when acted on by Thought." So the Will may be found acting unconsciously as an emotion or instinct, or developed with the highest forms of conscious reflection. Last of all we find it, probably as the result of all associated functions or powers, at the head of all, their Executive president. But _is_ it "the exponent of correlated forces?" There indeed doctors differ. There is a very curious Italian verb, _Invogliare_, which is thus described in a Dictionary of Idioms: "_Invogliare_ is to inspire a will or desire, _cupiditatem injicere a movere_. To _invogliare_ anyone is to awake in him the will or the ability or capacity, an earnest longing or appetite, an ardent wish--_alicujus rei cupiditatem a desiderium alicni movere_--to bring into action a man's hankering, solicitude, anxiety, yearning, ardor, predilection, love, fondness and relish, or aught which savors of Willing." Our English word, _Inveigle_, is derived from it, but we have none precisely corresponding to it which so generally sets forth the idea of inspiring a will in another person. "Suggestion" is far more general and vague. Now if a man could thus _in-will_ himself to good or moral purpose, he would assume a new position in life. We all admit that most human beings have defects or faults of which they would gladly be freed (however incorrigible they _appear_ to be), but they have not the patience to effect a cure, to keep to the resolve, or prevent it from fading out of sight. For a _vast_ proportion of all minor sins, or those within the law, there is no cure sought. The offender says and believes, "It is too strong for me"--and yet these small unpunished offenses cause a thousand times more suffering than all the great crimes.
