The greatest secret of monarchic rule...is to keep men deceived and to cloak in the specious name of religion the fear by which they must be checked, so that they will fight for slavery as they would for salvation, and will think it not shameful, but a most honorable achievement, to give their life and blood that one man may have a ground for boasting.
Baruch SpinozaMen would never be superstitious, if they could govern all their circumstances by set rules, or if they were always favoured by fortune: but being frequently driven into straits where rules are useless, and being often kept fluctuating pitiably between hope and fear by the uncertainty of fortune's greedily coveted favours, they are consequently for the most part, very prone to credulity.
Baruch SpinozaSince love of God is the highest felicity and happiness of man, his final end and the aim of all his actions, it follows that he alone observes the divine law who is concerned to love God not from fear of punishment nor love of something else, such as pleasure, fame, ect., but from the single fact that he knows God, or that he knows that the knowledge and love of God is the highest good
