"An action is an aim of the subject, and it is his agency too which executes this aim: unless the subject were in this way even in the most disinterested action, i.e. unless he had an interest in it, there would be no action at all.... Impulse and passion are the very life- blood of all action: they are needed if the agent is really to be in his aim and the execution thereof. The morality concerns the content of the aim, which as such is the universal, an inactive thing, that finds it actualizing in the agent."
"To hide a passion totally (or even to hide, more simply, its excess) is inconceivable: not because the human subject is too weak, but because passion is in essence made to be seen: the hiding must be seen: I want you to know that I am hiding something from you, that is the active paradox I must resolve: at one and the same time it must be known and not known: I want you to know that I don't want to show my feelings: that is the message I address to the other."
"What is passion? It is surely the becoming of a person. Are we not, for most of our lives, marking time? Most of our being is at rest, unlived. In passion, the body and the spirit seek expression outside of self. Passion is all that is other from self. Sex is only interesting when it releases passion. The more extreme and the more expressed that passion is, the more unbearable does life seem without it. It reminds us that if passion dies or is denied, we are partly dead and that soon, come what may, we will be wholly so."
"His breast was the seat of all those passions which degrade our nature, and disturb our reason. There they raged in a perpetual conflict; but avarice, the meanest of them all, generally triumphed, ruled absolutely, and in many instances, which I forbear to mention, most scandalously."
"We must not suppose that, because a man is a rational animal, he will, therefore, always act rationally; or, because he has such or such a predominant passion, that he will act invariably and consequentially in pursuit of it. No, we are complicated machines; and though we have one main spring that gives motion to the whole, we have an infinity of little wheels, which, in their turns, retard, precipitate, and sometime stop that motion."
"Spirit is now a very fashionable word: to act with Spirit, to speak with Spirit, means only to act rashly, and to talk indiscreetly. An able man shows his Spirit by gentle words and resolute actions; he is neither hot nor timid."
