“All those instances to be found in history, whether real or fabulous, of a doubtful public spirit, at which morality is perplexed, reason is staggered, and from which affrighted Nature recoils, are their chosen and almost sole examples for the instruction of their youth.”

Context: It was this spirit of the masses and the revolt of the poor which so often found voice in the words of Jesus. But these condemnations are not solely expressive of the intense heat that so often burns in the heart of great agitators and reformers, they are also expressions of the conviction of Jesus that material possessions corrupt and destroy the souls of men.... censure for the rich and love for the poor both in spirit and in worldly goods helped him to drive home a great truth that you cannot love God and mammon.

1850s
Context: The scepticism of the ancient world left no department of human belief unassailed. It took its chief stand upon the conflicting nature of the impressions of the senses, but threw the dark shade of uncertainty over the most settled convictions of the mind; over men's belief in an external world, over their consciousness of their own existence. But this form of doubt was not destined to endure. Science, in removing the contradictions of sense, and establishing the consistent uniformity of natural law, took away the main pillars of its support. The spirit, however, and the mental habits of which it was the roduct, still survive; but not among the votaries of science. For I cannot but regard it as the same spirit which, with whatever profession of zeal, and for whatever ends of supposed piety or obedience, strives to subvertthe natural evidences of morals, - the existence of a Supreme Intelligent Cause. There is a scepticism which repudiates all belief; there is also a scepticism which seeks to escape from itself by a total abnegation of the understanding, and which, in the pride of its new-found security, would recklessly destroy every internal ground of humant trust and hope... Now to this, as to a former development of the sceptical spirit, Science stands in implied but real antagonism.

Portrait of an Age (1936)

Letter 8; Variant: The greater part of men are much too exhausted and enervated by their struggle with want to be able to engage in a new and severe contest with error. Satisfied if they themselves can escape from the hard labour of thought, they willingly abandon to others the guardianship of their thoughts.
On the Aesthetic Education of Man (1794)
Context: Dare to be wise! Energy and spirit is needed to overcome the obstacles which indolence of nature as well as cowardice of heart oppose to our instruction. It is not without significance that the old myth makes the goddess of Wisdom emerge fully armed from the head of Jupiter; for her very first function is warlike. Even in her birth she has to maintain a hard struggle with the senses, which do not want to be dragged from their sweet repose. The greater part of humanity is too much harassed and fatigued by the struggle with want, to rally itself for a new and sterner struggle with error. Content if they themselves escape the hard labor of thought, men gladly resign to others the guardianship of their ideas, and if it happens that higher needs are stirred in them, they embrace with a eager faith the formulas which State and priesthood hold in readiness for such an occasion.
