Lecture VII

I mention all this to show what difficulties external science has and must have in getting to know the truth. It will draw certain conclusions and thus come near the truth. For some persons this will not be necessary, because science will gradually be supplemented by clairvoyant perception that does experience the difference between these forces and those active out in the three kingdoms of nature. At present I cannot deal fully with the superficial objection that animals also sleep. Such objections have little logical value but people do not notice it, nor their superficiality, for they judge according to concepts instead of the real nature of things. By introducing animal sleep into the argument one would speak the same fallacy as if someone were to say, “I sharpen my pencil with a knife and I also shave with a knife,” and another person replied, “That is impossible, knives are there to cut meat.” People are always making that kind of judgment. They think that a given thing must have the same function in different realms of nature. Sleep is an altogether different function in man from what it is in the animals.
