If we conceive that anyone loves, desires, or hates anything which we ourselves love, desire, or hate, we shall thereupon regard the thing in question with more steadfast love, etc. On the contrary, if we think that anyone shrinks from something that we love, we shall undergo vacillation of the soul.
Baruch SpinozaHuman infirmity in moderating and checking the emotions I name bondage : for, when a man is a prey to his emotions, he is not his own master, but lies at the mercy of fortune : so much so, that he is often compelled, while seeing that which is better for him, to follow that which is worse.
Baruch SpinozaNo one doubts but that we imagine time from the very fact that we imagine other bodies to be moved slower or faster or equally fast. We are accustomed to determine duration by the aid of some measure of motion.
