“The whole is a riddle, an aenigma, an inexplicable mystery. Doubt, uncertainty, suspence of judgment appear the only result of our most accurate scrutiny, concerning this subject.”

H. L. Mencken, Treatise on the Gods (1930)
Context: It was not until the Twelfth Century of our era that the Pentateuch as a whole was subjected to rational scrutiny. The man who undertook the ungrateful task was a learned Spanish rabbi, Abraham ben Meir ibn Esra. He unearthed many absurdities, but... it was not until five hundred years later that anything properly describable as scientific criticism... came into being. Its earliest shining lights were the English philosopher Thomas Hobbes [with his Leviathan], and the Amsterdam Jew, Baruch Spinoza. Spinoza's "Tractatus Theologico-politicus", published in 1670, made the first really formidable onslaught upon the inspired inerrancy of the Pentateuch. It called attention to scores of transparent imbecilities … including a dozen or more palpable geographical and historical impossibilities … The answer of constituted authorities was to suppress the "Tractatus", but enough copies got out to reach the proper persons, and ever since then the Old Testament has been under searching and devastating examination.

Pupils at Sais (1799)
Context: The waking man looks without fear at this offspring of his lawless Imagination; for he knows that they are but vain Spectres of his weakness. He feels himself lord of the world: his me hovers victorious over the Abyss; and will through Eternities hover aloft above that endless Vicissitude. Harmony is what his spirit strives to promulgate, to extend. He will even to infinitude grow more and more harmonious with himself and with his Creation; and at every step behold the all-efficiency of a high moral Order in the Universe, and what is purest of his Me come forth into brighter and brighter clearness. This significance of the World is Reason; for her sake is the World here; and when it is grown to be the arena of a childlike, expanding Reason, it will one day become the divine Image of her Activity, the scene of a genuine Church. Till then let man honour Nature as the Emblem of his own Spirit; the Emblem ennobling itself, along with him, to unlimited degrees. Let him, therefore, who would arrive at knowledge of Nature, train his moral sense, let him act and conceive in accordance with the noble Essence of his Soul; and as if of herself Nature will become open to him. Moral Action is that great and only Experiment, in which all riddles of the most manifold appearances explain themselves. Whoso understands it, and in rigid sequence of Thought can lay it open, is forever master of Nature.

On War (1832), Book 2

On Being a Real Person (1943)
Context: Every human life involves an unfathomable mystery, for man is the riddle of the universe, and the riddle of man is his endowment with personal capacities. The stars are not so strange as the mind that studies them, analyzes their light, and measures their distances.

Reflections on the Revolution in France (1790)
Context: Where popular authority is absolute and unrestrained, the people have an infinitely greater, because a far better founded, confidence in their own power. They are themselves, in a great measure, their own instruments. They are nearer to their objects. Besides, they are less under responsibility to one of the greatest controlling powers on the earth, the sense of fame and estimation. The share of infamy that is likely to fall to the lot of each individual in public acts is small indeed; the operation of opinion being in the inverse ratio to the number of those who abuse power. Their own approbation of their own acts has to them the appearance of a public judgment in their favor. A perfect democracy is, therefore, the most shameless thing in the world. As it is the most shameless, it is also the most fearless. No man apprehends in his person that he can be made subject to punishment.

Part 1, Section 1
A Treatise of Human Nature (1739-40), Book 3: Of morals
Context: Morality is a subject that interests us above all others: We fancy the peace of society to be at stake in every decision concerning it; and 'tis evident, that this concern must make our speculations appear more real and solid, than where the subject is, in a great measure, indifferent to us. What affects us, we conclude can never be a chimera; and as our passion is engag'd on the one side or the other, we naturally think that the question lies within human comprehension; which, in other cases of this nature, we are apt to entertain some doubt of. Without this advantage I never should have ventur'd upon a third volume of such abstruse philosophy, in an age, wherein the greatest part of men seem agreed to convert reading into an amusement, and to reject every thing that requires any considerable degree of attention to be comprehended.
