Passion, as a philosophical concept is identified with an innate or biologically driven emotional states such as anger, greed, lust or the other deadly sins, and is different from the modern romantic connotations of the word.
The seventeenth century Dutch philosopher Spinoza described the distinction between action and passion, as well as the state of being active and the state of being passive. Passion is the result of confused ideas about the causes and effects of any events that affect us.
Still passion can hence be equated with quietism or a state of quietness and passivity that accepts whatever God sends and values silent contemplation. Quietism is also a form of Christian mysticism characterized by passive contemplation and the destruction of the human will in face of the divine will.
