Happiness in the main is a pleasant, contented condition of the mind, that is to say, "a state of mind." To be perfect, as appears from an enlarged study of all things or phenomena in their relations (since every part must harmonize with the whole), this happiness implies duty and altruism, every whit as much as self-enjoyment. This agrees with and results from scientific experience. Under the old _a priori_ psychologic system, _selfishness_ (which meant that every soul was to be chiefly or solely concerned in saving itself, guided by hope of reward and fear of punishment), it was naturally the basis of morality. Now, accepting the definition of Happiness as a state of mind under certain conditions, it follows that it can be realized to a great degree, and in all cases to some degree, firstly by forethought or carefully defining what it is or what we desire, and secondly by making a fixed idea by simple, well-nigh mechanical means, without any resource to _les grands moyens_. According to the old and now rapidly vanishing philosophy, this was to be effected by sublime morality, prayer, or adjuration of supernatural beings and noble heroism, but what is here proposed is much humbler, albeit more practical. Reading immortal poetry or prose is indeed a splendid power, but to learn the letters of the alphabet, and to spell, is very simple and unpoetic, yet far more practical. What I have described has been the mere dull rudiments. It is most remarkable that the world has always known that the art of RAFFAELLE, MICHAEL ANGELO, and ALBERT DURER was based, like that of the greatest musicians, on extensive rudimentary study, and yet has never dreamed that what far surpasses all art in every way, and even includes the desire for it, may all proceed from, or be developed by, a process which is even easier than those required for the lesser branches. He who can control his own mind by an iron will, and say to the Thoughts which he would banish, "Be ye my slaves and begone into outer darkness," or to Peace "Dwell with me forever, come what may," _and be obeyed_, that man is a mighty magician who has attained what is worth more than all that Earth possesses. Absolute self-control under the conditions before defined--since our happiness to be true must agree with that of others--is absolutely essential to happiness. There can be no greater hero than the man who can conquer himself and think exactly as he pleases. That which annoys, tempts, stirs us to being irritable, wicked, or mean, is an aggregate of evil thoughts or images received by chance or otherwise into the memory, developed there into vile unions, and new forms like coalescing animalcule, and so powerful and vivid or objective do they become that men in all ages have given them a real existence as evil spirits.
