She instead is always cold, derides every form of enthusiasm, because it seems to her a species of madness; detests poetry, all psychical pleasures, and all passions when they pass 10° Centigrade; derides heroism, sacrifice, and martyrdom, contenting herself by declaring it to be the matter of a novel or a stage play. And these two—can they live happily together? These few examples, taken from the stage of the real world, will be sufficient to give you an idea of the many discords of character one finds in the union of marriage. Certainly all are not so flagrant or so keenly accentuated, but they are more complex and complicated, whilst the discord is rarely upon one note only, but upon many together. And what can we do to defend ourselves from the peril of _incompatibility of temper_? In one way only: by studying and restudying the character of her whom we wish to make our companion for life. After being convinced that she will show herself better than she really is we must make every effort to surprise her in undress, or, better still, in a state of nudity. Naturally I speak in a figurative sense. I should wish to see her nude of all artifices of coquetry and hypocrisy. Begin to examine the moral surroundings in which she lives, and before studying her study the future father- and mother-in-law. She is only a branch of that plant upon which you wish to graft your life, and a great part of the children’s character is that of their parents. It is exceedingly rare for a loose, libertine mother to have a chaste daughter, and a lily of innocence is hardly ever born into a family of impostors. We have spendthrift sons of a miserly father, and _vice versa_; bigoted children of atheistic parents, and disbelievers sons of bigots; but as regards moral habits there is very rarely the heredity of antagonism. Examine especially the moral surroundings in which the young girl was born and has grown up; her habits, the books she reads, the amusements she prefers. Gain information as to the character of her friends, for in them as in a glass you will often see the soul of the woman you wish to make yours. I know an angelic woman with many friends who vie with each other in loving her, and are jealous one of the other for her affection. These friends are all unusual women, of refined tastes, delicate feelings, and generous hearts. They all chaunt her virtues in chorus, and, without knowing, I judged her from her friends to be an angel, and I was not mistaken. After having made your psychological research as regards her parents and friends do not disdain to descend to a more humble sphere. Question her maid, cook, coachman, dressmaker, and the labourers on her estate: all those who for one reason or another serve and obey her.
