“The boundaries which divide Life from Death are at best shadowy and vague. Who shall say where the one ends, and where the other begins?”

Ce monde commence où l'épouse légale finit, et il finit où l'épouse vénale commence, il est séparé des honnêtes femmes par le scandale, des courtisanes par l'argent.

Man's Rise to Civilization (1968)
Context: The debate as to where "magic" ends and "religion" begins is an old one, and it appeared to have been settled some decades ago when scholars concluded that no discernible boundary was to be found. As a result, the two were often lumped together in the adjective "magico-religious"...

A Vindication of Natural Society (1756)
Context: A good parson once said, that where mystery begins, religion ends. Cannot I say, as truly at least, of human laws, that where mystery begins, justice ends? It is hard to say whether the doctors of law or divinity have made the greater advances in the lucrative business of mystery. The lawyers, as well as the theologians, have erected another reason besides natural reason; and the result has been, another justice besides natural justice. They have so bewildered the world and themselves in unmeaning forms and ceremonies, and so perplexed the plainest matters with metaphysical jargon, that it carries the highest danger to a man out of that profession, to make the least step without their advice and assistance. Thus, by confining to themselves the knowledge of the foundation of all men's lives and properties, they have reduced all mankind into the most abject and servile dependence. We are tenants at the will of these gentlemen for everything; and a metaphysical quibble is to decide whether the greatest villain breathing shall meet his deserts, or escape with impunity, or whether the best man in the society shall not be reduced to the lowest and most despicable condition it affords. In a word, my Lord, the injustice, delay, puerility, false refinement, and affected mystery of the law are such, that many who live under it come to admire and envy the expedition, simplicity, and equality of arbitrary judgments.
