much less original figure, has hitherto stood in the way of the general recognition of his great importance for modern philosophy.

Human knowledge and the relation of God to the world are the two poles of the Cusan's system. He distinguishes four stages of knowledge. Lowest of all stands sense (together with imagination), which yields only confused images; next above, the understanding (ratio), whose functions comprise analysis, the positing of time and space, numerical operations, and denomination, and which keeps the opposites distinct under the law of contradiction; third, the speculative reason (intellectus), which finds the opposites reconcilable; and highest of all the mystical, supra-rational intuition (visio sine comprehensione, intuitio, unio, filiatio), for which the opposites coincide in the infinite unity. The intuitive culmination of knowledge, in which the soul is united with God,—since here even the antithesis of subject and object disappears,—is but seldom attained; and it is difficult to keep out the disturbing symbols and images of sense, which mingle themselves in the intuition. But it is just this insight into the incomprehensibility of the infinite which gives us a true knowledge of God; this is the meaning of the "learned ignorance," the docta ignorantia. The distinctions between these several stages of cognition are not, however, to be understood in any rigid sense, for each higher function comprehends the lower, and is active therein. The understanding can discriminate only when it is furnished by sensation with images of that which is to be discriminated, the reason can combine only when the understanding has supplied the results of analysis as material for combination; while, on the other hand, it is the understanding which is present in sense as consciousness, and the reason whose unity guides the understanding in its work of separation. Thus the several modes of cognition do not stand for independent fundamental faculties, but for connected modifications of one fundamental power which work together and mutually imply one another. The position that an intellectual function of attention and discrimination is active in sensuous perception, is a view entirely foreign to mediaeval modes of thought; for the Scholastics were accustomed to make sharp divisions between the cognitive faculties, on the principle that particulars are felt through sense and universals thought through the understanding. The idea on which Nicolas bases his argument for immortality has also an entirely modern sound: viz., that space and time are products of the understanding, and, therefore, can have no power over the spirit which produces them; for the author is higher and mightier than the product.

The confession that all our knowledge is conjecture does not simply mean that absolute and exact truth remains concealed from us; but is intended at the same time to encourage us to draw as near as possible to the eternal verity by ever truer conjectures. There are degrees of truth, and our surmises are neither absolutely true nor entirely false. Conjecture becomes error only when, forgetting the inadequacy of human knowledge, we rest content with it as a final solution; the Socratic maxim, "I know that I am ignorant," should not lead to despairing resignation but to courageous further inquiry. The duty of speculation is to penetrate deeper and deeper into the secrets of the divine, even though the ultimate revelation will not be given us until the hereafter. The fittest instrument of speculation is furnished by mathematics, in its conception of the infinite and the wonders of numerical relations: as on the infinite sphere center and circumference coincide, so God's essence is exalted above all opposites; and as the other numbers are unfolded from the unit, so the finite proceeds by explication from the infinite. A controlling significance in the serial construction of the world is ascribed to the ten, as the sum of the first four numbers—as reason, understanding, imagination, and sensibility are related in human cognition, so God, spirit, soul, and body, or infinity, thought, life, and being are related in the objective sphere; so, further, the absolute necessity of God, the concrete necessity of the universe, the actuality of individuals, and the possibility of matter. Beside the quaternary the tern also exercises its power—the world divides into the stages of eternity, imperishability, and the temporal world of sense, or truth, probability, and confusion. The divine trinity is reflected everywhere: in the world as creator, created, and love; in the mind as creative force, concept, and will. The triunity of God is very variously explained—as the subject, object, and act of cognition; as creative spirit, wisdom, and goodness; as being, power, and deed; and, preferably, as unity, equality, and the combination of the two.

God is related to the world as unity, identity, complicatio, to otherness, diversity, explicatio, as necessity to contingency, as completed actuality to mere possibility; yet, in such a way that the otherness participates in the unity, and receives its reality from this, and the unity does not have the otherness confronting it, outside it. God is triune only as the Creator of the world, and in relation to it; in himself he is absolute unity and infinity, to which nothing disparate stands opposed, which is just as much all things as not all things, and which, as the Areopagite had taught of old, is better comprehended by negations than by affirmations. To deny that he is light, truth, spirit, is more true than to affirm it, for he is infinitely greater than anything which can be expressed in words; he is the Unutterable, the Unknowable, the supremely one and the supremely absolute. In the world, each thing has things greater and smaller by its side, but God is the absolutely greatest and smallest; in accordance with the principle of the coincidentia oppositorum, the absolute maximum and the absolute minimum coincide. That which in the world exists as concretely determinate and particular, is in God in a simple and universal way; and that which here is present as incompleted striving, and as possibility realizing itself by gradual development, is in God completed activity. He is the realization of all possibility, the Can-be or Can-is (possest); and since this absolute actuality is the presupposition and cause of all finite ability and action, it may be unconditionally designated ability (posse ipsum), in antithesis to all determinate manifestations of force; namely, to all ability to be, live, feel, think, and will.

However much these definitions, conceived in harmony with the dualistic view of Christianity, accentuate the antithesis between God and the world, this is elsewhere much softened, nay directly denied, in favor of a pantheistic view which points forward to the modern period. Side by side with the assertion that there is no proportion whatever between the infinite and the finite, the following naïvely presents itself, in open contradiction to the former: God excels the reason just as much as the latter is superior to the understanding, and the understanding to sensibility, or he is related to thought as thought to life, and life to being. Nay, Nicolas makes even bolder statements than these,
