Satan is not seen as a strictly evil force in the wesoteric tradition. S/he is more the earthly passions which motivate us to action and sheds the light of knowledge, and is only 'evil' when unbalanced. Freemason Albert Pike, in his masterpiece Morals and Dogma, wrote this in the preamble:
"LUCIFER, the Light-bearer! Strange and mysterious name to give to the Spirit of Darknesss! Lucifer, the Son of the Morning! Is it he who bears the Light, and with its splendors intolerable blinds feeble, sensual or selfish Souls ? Doubt it not!"
Aleister Crowley said of this (d)archetype in the Book of Thoth:
"This card represents creative energy in its most material form; in the Zodiac, Capricornus occupies the Zenith. It is the most exalted of the signs; it is the goat leaping with lust upon the summits of earth. The sign is ruled by Saturn, who makes for selfhood and perpetuity. In this sign, Mars is exalted, showing in its best form the fiery, material energy of creation. The card represents Pan Pangenetor, the All-Begetter. It is the Tree of Life as seen against a background of the exquisitely tenuous, complex, and fantastic forms of madness, the divine madness of spring, already foreseen in the meditative madness of winter; for the Sun turns northwards on entering this sign."
"The formula of this card is then the complete appreciation of all existing things. He rejoices in the rugged and the barren no less than in the smooth and the fertile. All things equally exalt him. He represents the finding of ecstasy in every phenomenon, however naturally repugnant; he transcends all limitations; he is Pan; he is All."
