The distinction between God with the Son, or the sensuous God, and God without the Son, or God divested of sensuousness, is nothing further than the distinction between the mystical and the rational man. The rational man lives and thinks; with him life is the complement of thought, and thought the complement of life, both theoretically, inasmuch as he convinces himself of the reality of sensuousness through the reason itself, and practically, inasmuch as he combines activity of life with activity of thought. That which I have in life, I do not need to posit beyond life, in spirit, in metaphysical existence, in God; love, friendship, perception, the world in general, give me what thought does not, cannot give me, nor ought to give me. Therefore I dismiss the needs of the heart from the sphere of thought, that reason may not be clouded by desires;--in the demarcation of activities consists the wisdom of life and thought;--I do not need a God who supplies by a mystical, imaginary physicalness or sensuousness the absence of the real. My heart is satisfied before I enter into intellectual activity; hence my thought is cold, indifferent, abstract, i.e., free, in relation to the heart, which oversteps its limits, and improperly mixes itself with the affairs of the reason. Thus I do not think in order to satisfy my heart, but to satisfy my reason, which is not satisfied by the heart; I think only in the interest of reason, from pure desire of knowledge, I seek in God only the contentment of the pure, unmixed intelligence. Necessarily, therefore, the God of the rational thinker is another than the God of the heart, which in thought, in reason, only seeks its own satisfaction. And this is the aim of the mystic, who cannot endure the luminous fire of discriminating and limiting criticism; for his mind is always beclouded by the vapours which rise from the unextinguished ardour of his feelings. He never attains to abstract, i.e., disinterested, free thought, and for that reason he never attains to the perception of things in their naturalness, truth, and reality.
