118 AN INTRODUCTION TO SUFI DOCTRINE away from the Intellect, which transcends the terrestrial plane, it can only have a destructive character, like that of a corrosive acid, which destroys the organic unity of beings and of things. We have only to look at the modern world with its artificial character devoid of beauty and its inhumanly abstract and quantitative structure in order to know the character of thought when given over to its own resources. Man, the “thinking animal,” must necessarily be either the divine crown of nature or its adversary,! and this is so because in the mind “to be” becomes dissociated from *to know’’ and in the process of man’s degeneration this leads to all other ruptures and separations. This double property of thought corresponds to the principle which Sufis symbolise by the barzakh, the “ jsthmus” between two oceans. The barzakh is both a barrier and a point of junction between two degrees of reality. As an intermediate agent it reverses the pencil of rays of the light it transmits in the same manner as does a lens. In the structure of thought this inversion appears as abstraction. Thought is only capable of synthesis by stripping itself of the immediate aspect of things ; the more nearly it approaches the universal the more it is reduced as it were to a point. Thought thus imitates on the level of form—and hence imperfectly— 1. In animals there does not exist, as in man, a refraction of the intellect which is at the same time subjective and active, a refraction which would stand between the intellectual essence immanent in the form of the species and the individuel psychic organism. For this reason animals are more passive than man in relation to the cosmic surroundings. At the same time they more direct- ly express their intellectual essence. The beauty of a sacred art—an art divinely inspired—heightens that of virgin nature, while the creations of a civilisition that is profane-and practically atheistical, such as modern civilisation, are always hostile to natural harmony.
