That's not a spoiler and it's incorrect. Esper existed before magicians, who tried to emulate their power with magic and there is also the Pure World of science, so science came before magic. Said that, Aleister surely applied magical knowldege (like the Tree of Sephirot and Gnosticism) in his plan and in AC's esper powers development (proof of this are the Awakening, the Imaginary Number District and Kazakiri), but they are scientifical; magic-based scientifical powers if you prefer, but still scientifical.
