Although LaVey's ideas were largely shaped around a secular and scientific world-view, he also expressed a belief in magic. Rather than characterising magic as a supernatural phenomenon, LaVey expressed the view that it was a part of the natural world thus far undiscovered by scientists. Outlined in "The Satanic Bible", LaVey defined magic as "the change in situations or events in accordance with one's will, which would, using normally accepted methods, be unchangeable", a definition that reflects the influence of the British occultist Aleister Crowley. Although he never explained exactly how he believed that this magical process worked, LaVey stated that magicians could successfully utilise this magical force through intensely imagining their desired goal and thus directing the force of their own willpower toward it. He emphasised the idea that magical forces could be manipulated through "purely emotional" rather than intellectual acts.
