Sed amor erga rem aeternam et infinitam sola laetitia pascit animum, ipsaque omnis tristitiae est expers; quod valde est desiderandum totisque viribu… - Benedictus de Spinoza

Spinoza's ethics has nothing to do with a morality; he conceives it as an ethology, that is, as a composition of fast and slow speeds, of capacities for affecting and being affected on this plane of immanence. That is why Spinoza calls out to us in the way he does: you do not know beforehand what good or bad you are capable of; you do not know beforehand what a body or a mind can do, in a given encounter, a given arrangement, a given combination.

I read Spinoza's Ethics for the first time when I was thirteen years old. Of course at school we studied the Bible – which for me is the ultimate philosophical work. However, reading Spinoza opened up a new dimension for me, which is the reason for my continuing dedication to his works. Spinoza's simple principle 'man thinks' has become an existential mindset for me; my copy of his Ethics has become dog-eared and torn. For years I took it with me on my travels and in hotel rooms or intervals in concerts became absorbed by many of its principles. Spinoza's Ethics is the best training ground for the intellect, above all because Spinoza teaches the radical freedom of thought more completely than any other philosopher. This Spinozan brand of freedom is not a release from discipline into arbitrariness of thought, but an active process. The more one is able to determine one's own thoughts – in fact, causing one's own thoughts, thereby creating one's own experience of reality – the more it is possible to become self-determined, to be truly free.

...As to feeling a difference in Jews, I feel it I think, only if they do; and then it doesn't signify a preference or the opposite, but only a diversity. My best pupils were Jews, as was my only modern “master” in philosophy, Spinoza. But many are not happy, and that is a pity.
