“Those who do succeed in reading the Bible from beginning to end will discover that at least it has a beginning and an end, and some traces of a total structure.”

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.

Posthumous publications, The Collected Works
Context: To understand oneself requires patience, tolerant awareness; the self is a book of many volumes which you cannot read in a day, but when once you begin to read, you must read every word, every sentence, every paragraph for in them are the intimations of the whole. The beginning of it is the ending of it. If you know how to read, supreme wisdom is to be found.
