Introduction
Spinoza has exactly the same thing in mind when he describes the highest activity of cognition as that which advances “from the sufficient conception of the real nature of some attributes of God to the sufficient cognition of the nature of things.” This advance is nothing other than illumination of things with the light of inner experience. Spinoza describes the life of this inner experience in glorious colors: “The highest virtue of the soul is to apprehend God, or to comprehend things in the third—the highest—kind of cognition. This virtue becomes the greater the more the soul comprehends things in this way of cognition; therefore the one who grasps things in this way of cognition attains the highest human perfection and consequently becomes filled with the highest joy, accompanied by the conceptions of himself and of virtue. Hence from this kind of cognition springs the highest possible peace of soul.” One who comprehends things in this way transforms himself within himself; for at such moments his separate I is absorbed by the All-I; all beings do not appear in subordination to a separate, limited individual; they appear to themselves. At this level there is no longer any difference between Plato and me; what separates us belongs to a lower level of cognition. We are only separate as individuals; the universal which acts in us is one and the same. About this fact also one cannot dispute with one who has no experience of it. He will always insist: Plato and you are two. That this duality, that all multiplicity is reborn as unity in the unfolding of the highest level of cognition, cannot be proved: it must be experienced. Paradoxical as it may sound, it is true: the idea which Plato represented to himself and the same idea which I represent to myself are not two ideas. They are one and the same idea. And there are not two ideas, one in Plato's head, the other in mine; rather in the higher sense Plato's head and mine interpenetrate; all heads which grasp the same, single idea, interpenetrate; and this unique idea exists only once. It is there, and the heads all transport themselves to one and the same place in order to contain this idea.
