The life of God — the life which the mind apprehends and enjoys as it rises to the absolute unity of all things — may be described as a play of love with itself; but this idea sinks to an edifying truism, or even to a platitude, when it does not embrace in it the earnestness, the pain, the patience, and labor, involved in the negative aspect of things.

Opinion considers the opposition of what is true and false quite rigid, and, confronted with a philosophical system, it expects agreement or contradiction. And in an explanation of such a system, opinion still expects to find one or the other.

With Leibnitz the extent to which thoughts advance is the extent of the universe; where comprehension ceases, the universe ceases, and God begins: so that later it was even maintained that to be comprehended was derogatory to God, because He was thus degraded into finitude. In that procedure a beginning is made from the determinate, this and that are stated to be necessary; but since in the next place the unity of these moments is not comprehended, it is transferred to God. God is therefore, as it were, the waste channel into which all contradictions flow: Leibnitz's Théodicée is just a popular summing up such as this.

The second point to be considered is the method adopted by Spinoza for setting forth his philosophy; it is the demonstrative method of geometry as employed by Euclid, in which we find definitions, explanations, axioms, and theorems. Even Descartes made it his starting-point that philosophic propositions must be mathematically handled and proved, that they must have the very same evidence as mathematics. The mathematical method is considered superior to all others, on account of the nature of its evidence; and it is natural that independent knowledge in its re-awakening lighted first upon this form, of which it saw so brilliant an example. The mathematical method is, however, ill-adapted for speculative content, and finds its proper place only in the finite sciences of the understanding. In modern times Jacobi has asserted (Werke, Vol. IV. Section I. pp. 217-223) that all demonstration, all scientific knowledge leads back to Spinozism, which alone is a logical method of thought; and because it must lead thither, it is really of no service whatever, but immediate knowledge is what we must depend on. It may be conceded to Jacobi that the method of demonstration leads to Spinozism, if we understand thereby merely the method of knowledge belonging to the understanding. But the fact is that Spinoza is made a testing-point in modern philosophy, so that it may really be said: You are either a Spinozist or not a philosopher at all. This being so, the mathematical and demonstrative method of Spinoza would seem to be only a defect in the external form; but it is the fundamental defect of the whole position. In this method the nature of philosophic knowledge and the object thereof, are entirely misconceived, for mathematical knowledge and method are merely formal in character and consequently altogether unsuited for philosophy. Mathematical knowledge exhibits its proof on the existent object as such, not on the object as conceived; the Notion is lacking throughout; the content of Philosophy, however, is simply the Notion and that which is comprehended by the Notion. Therefore this Notion as the knowledge of the essence is simply one assumed, which falls within the philosophic subject; and this is what represents itself to be the method peculiar to Spinoza's philosophy.

If there are different Notions of the science of Philosophy, it is the true Notion alone that puts us in a position to understand the writings of philosophers who have worked in the knowledge of it. For in thought, and particularly in speculative thought, comprehension means something quite different from understanding the grammatical sense of the words alone, and also from understanding them in the region of ordinary conception only. Hence we may possess a knowledge of the assertions, propositions, or of the opinions of philosophers; we may have occupied ourselves largely with the grounds of and deductions from these opinions, and the main point in all that we have done may be wanting — the comprehension of the propositions

The possession of self-conscious reason, which belongs to us of the present world, did not arise suddenly, nor did it grow only from the soil of the present. This possession must be regarded as previously present, as an inheritance, and as the result of labour — the labour of all past generations of men. Introduction p. 2

What the history of Philosophy shows us is a succession of noble minds, a gallery of heroes of thought, who, by the power of reason, have penetrated into the being of things, of nature and of spirit, into the Being of God, and have won for us by their labours the highest treasure, the treasure of reasoned knowledge. Introduction p. 1

The Being of the universe, at first hidden and concealed, has no power which can offer resistance to the search for knowledge ; it has to lay itself open before the seeker — to set before his eyes and give for his enjoyment, its riches and its depths. p xii

It may indeed be said that since Philosophy began to take a place in Germany, it has never looked so badly as at the present time — never have emptiness and shallowness overlaid it so completely, and never have they spoken and acted with such arrogance, as though all power were in their hands ! To combat the shallowness, to strive with German earnestness and honesty, to draw Philosophy out of the solitude into which it has wandered — to do such work as this we may hope that we are called by the higher spirit of our time. p. xi

The necessities of the time have accorded to the petty interests of every day life such overwhelming attention : the deep interests of actuality and the strife respecting these have engrossed all the powers and the forces of the mind — as also the necessary means — to so great an extent, that no place has been left to the higher inward life, the intellectual operations of a purer sort; and the better natures have thus been stunted in their growth, and in great measure sacrificed. p. x

A command can express no more than an ought or a shall, because it is a universal, but it does not express an ‘is’; and this at once makes plain its deficiency. Against such commands Jesus sets virtue, i.e., a loving disposition, which makes the content of the command superfluous and destroys its form as a command, because that form implies an opposition between a commander and something resisting the command.
