Better that right counsels be known to enemies than that the evil secrets of tyrants should be concealed from citizens. - Benedictus de Spinoza

Nothing in Nature is random. A thing appears random only through the incompleteness of our knowledge.

That I might investigate the subject matter of this science with the same freedom of spirit we generally use in mathematics, I have labored carefully not to mock, lament, or execrate human actions, but to understand them; and to this end I have looked upon passions such as love, hatred, anger, envy, ambition, pity, and other perturbations of the mind, not in the light of vices of human nature, but as properties just as pertinent to it as are heat, cold, storm, thunder, and the like to the nature of the atmosphere.

What Spinoza regards as ‘true religion’ and ‘true piety’ requires no belief in any historical events, supernatural incidents or metaphysical doctrines, and it prescribes no devotional rites. It does not demand accepting any particular theology of God's nature or philosophical claims about the cosmos and its origins. The divine law directs us only on how to behave with justice and charity toward other human beings. ‘[We are] to uphold justice, help the helpless, do no murder, covet no man's goods, and so on’. All the other rituals or ceremonies of the Bible's commandments are empty practices that ‘do not contribute to blessedness and virtue’. True religion is nothing more than moral behaviour. It is not what you believe, but what you do that matters. Writing to the Englishman and secretary to the Royal Society Henry Oldenburg in 1675, Spinoza says that ‘the chief distinction I make between religion and superstition is that the latter is founded on ignorance, the former on wisdom’.
