“Where?” on the other hand can have no meaning for a plant existence. It is the question with which awakening man daily orients himself afresh with respect to the world. For it is only the pulse-beat of Being that endures throughout the generations, whereas waking-consciousness begins anew for each microcosm. And herein lies the distinction between procreation and birth, the first being a pledge of duration, the second a beginning. A plant, therefore, is bred, but it is not born. It “is there,” but no awakening, no birthday, expands a sense-world around it. II With this we are brought face to face with man. In man’s waking-consciousness nothing disturbs the now pure lordship of the eye. The sounds of the night, the wind, the panting of beasts, the odour of flowers, all stimulate in him _a “whither” and a “whence” in the world of light_. Of the world of scent, in which even our closest comrade the dog still co-ordinates his visual impressions, we have no conception whatever. We know nothing of the world of the butterfly, whose crystalline eye projects no synthetic picture, or of those animals which, while certainly not destitute of senses, are blind. _The only space that remains to us is visual space_, and in it places have been found for the relics of other sense-worlds (such as sounds, scents, heat and cold) as _properties and effects of light-things_--it is a seen fire that warmth comes from, it is a seen rose in illumined space that gives off the scent and we speak of a certain tone as violin-tone. As to the stars, our conscious relations with them are limited to seeing them--over our heads they shine, describing their visible path.[4] But of these sense-worlds there is no doubt that animals and even primitive men still have sensations that are wholly different from ours; some of these sensations we are able to figure to ourselves indirectly by the aid of scientific hypotheses, but the rest now escape us altogether.
