"The fundamental maxim of those who stand at the head of this Age, and therefore the principle of the Age, is this,—to accept nothing as really existing or obligatory, but that which they can understand and clearly comprehend. With regard to this fundamental principle, as we have now declared and adopted it without farther definition or limitation, this third Age is precisely similar to that which is to follow it, the fourth, or age of Reason as Science,—and by virtue of this similarity prepares the way for it. Before the tribunal of Science, too, nothing is accepted but the Conceivable. Only in the application of the principle there is this difference between the two Ages,—that the third, which we shall shortly name that of Empty Freedom, makes its fixed and previously acquired conceptions the measure of existence; while the fourth—that of Science—on the contrary, makes existence the measure, not of its acquired, but of its desiderated beliefs."

“The will is the living principle of the rational soul, is indeed itself reason, when purely and simply apprehended. That reason is itself active, means, that the pure will, as such, rules and is effectual. The infinite reason alone lies immediately and entirely in the purely spiritual order. The finite being lives necessarily at the same time in a sensuous order; that is to say, in one which presents to him other objects than those of pure reason; a material object, to be advanced by instruments and powers, standing indeed under the immediate command of the will, but whose efficacy is conditional also on its own natural laws.”

“The Doctrine of a Perfect God; in whose nature nothing arbitrary or changeable can have a place; in whose Highest Being we all live, and in this Life may, and ought at all times to be, blessed;—this Doctrine, which ignorant men think they have sufficiently demolished when they have proclaimed it to be Mysticism, is by no means Mysticism, for it has an immediate reference to human action, and in deed to the inmost spirit which ought to inspire and guide all our actions. It can only become Mysticism when it is associated with the pretext that the insight into this truth proceeds from a certain inward and mysterious light, which is not accessible to all men, but is only bestowed upon a few favourites chosen from among the rest:—in which pretext the Mysticism consists, for it betrays a presumptuous contemplation of personal merit, and a pride in mere sensuous Individuality.”

“History is mere Empiricism; it has only facts to communicate, and all its proofs are founded upon facts alone. To attempt to rise to Primeval History on this foundation of fact, or to argue by this means how such or such a thing might have been, and then to take for granted that it has been so in reality,is to stray beyond the limits of History, and produce an a priori History; just as the Philosophy of Nature, referred to in our preceding lecture, endeavoured to find an a priori Science of Physics.”

“True Religion does not manifest itself outwardly, and impels man to no course of external conduct which he would not otherwise have adopted, but that it only completes his true In ward Being and Dignity. It is neither an Action, nor an incentive to Action, but a Thought:—it is LIGHT, and the One True Light, which bears within it all Life and all the forms of Life, and pervades their innermost substance. Once arisen, this Light flows on spontaneously forever, spreading itself forth without term or limit;-and it is as idle to bid it shine, as it would be to address such a command to the material sun when it stands in the noon-day heavens. It does this without our bidding; and if it shine not, then has it not arisen. At its uprising, Darkness, and the brood of spectres and phantasms which are born of Darkness, vanish of themselves.”

“The supervision of the state extends to the lock upon the door, and there begins mine own. The lock is the boundary line between the power of the government and my own private power. It is the intention of locks to make possible self-protection. In my own house my person is sacred and inviolable even to the government. In civil cases government has no right to attack me in my house, but must wait till I am upon public ground.”

“What is the use of all knowledge, if one does not act in accordance with it? This remark implies that knowledge is regarded as a means to action, and the latter as the real end. One could put the question the other way round and ask: How can we possibly act well without knowing what the Good is? This way of expressing it would regard knowledge as conditioning action. But both expressions are one-sided, and the truth is that both, knowledge as well as action, are in the same way inseparable elements of rational life.”
