"The slow, the never ending approach to truth consists in perpetually forming and testing hypotheses, accepting those at which at the time seem to fit the facts and rejecting the others."

"In primitive society, where uniformity of occupation is the rule, and the distribution of the community into various classes of workers has hardly begun, every man is more or less his own magician; he practices charms and incantations for his own good and the injury of his enemies."

"I am a plain practical man, not one of your theorists and splitters of hairs and choppers of logic."

"Small minds cannot grasp great ideas; to their narrow comprehension, their purblind vision, nothing seems really great and important but themselves. Such minds hardly rise into religion at all."

"If the test of truth lay in a show of hands or a counting of heads, the system of magic might appeal, with far more reason than the Catholic Church, to the proud motto, Quod semper, quod ubique, quod ab omnibus [always, everywhere, and by all], as the sure and certain credential of its own infallibility."

"We seem to move on a thin crust which may at any moment be rent by the subterranean forces slumbering below."

"Ancient magic was the very foundation of religion."

"By religion, then, I understand a propitiation or conciliation of powers superior to man which are believed to direct and control the course of nature and of human life."

"From the earliest times man has been engaged in a search for general rules whereby to turn the order of natural phenomena to his own advantage, and in the long search he has scraped together a great hoard of such maxims, some of them golden and some of them mere dross. The true or golden rules constitute the body of applied science which we call the arts; the false are magic."

"The old notion that the savage is the freest of mankind is the reverse of the truth. He is a slave, not indeed to a visible master, but to the past, to the spirits of his dead forefathers, who haunt his steps from birth to death, and rule him with a rod of iron."

"If in the present work I have dwelt at some length on the worship of trees, it is not, I trust, because I exaggerate its importance in the history of religion, still less because I would deduce from it a whole system of mythology; it is simply because I could not ignore the subject in attempting to explain the significance of a priest who bore the title of King Of the Wood, and one of whose titles to office was the plucking of a bough — the Golden Bough — from a tree in the sacred grove."

"A candidate for the priesthood could only succeed to office by slaying the priest, and having slain him, he retained office till he was himself slain by a stronger or a craftier."

"It is for the philosophic student to trace the train of thought which underlies the magicians practice; to draw out the few simple threads of which the tangled skein is composed; to disengage the abstract principles from their concrete applications; in short, to discern the spurious science from the bastard art."

"If we analyze the principles of thought on which magic is based, they will probably be found to resolve themselves into two: first, that like produces like, or that an effect resembles its cause; and, second, that things which have once been in contact with each other continue to act on each other at a distance after the physical contact has been severed. The former principle may be called the Law of Similarity, the latter the Law of Contact or Contagion. From the first of these principles, namely the Law of Similarity, the magician infers that he can produce any effect he desires merely by imitating it: from the second he infers that whatever he does to a material object will affect equally the person with whom the object was once in contact, whether it formed part of his body or not."
