The Essence of Anthroposophy

Now, no spiritual research could possibly make any impression or exert any fruitful influence in the long term if it were to contradict the significant developments that have taken place over the last three to four centuries, and particularly in the nineteenth century, through natural science and its practical results. But that is certainly not what anthroposophy wants. It seeks to follow into the spiritual world the very paths that have led to significant results in natural science. It must therefore side with those natural scientists, the level-headed natural scientists, who, after thoroughly pursuing the paths of natural science, speak of the limitations of natural science. These limits soon become apparent when one considers that natural science can only observe the external sense world, can only combine the facts of the external sense world that arise from observation or experiment through the intellect, through the mind, and then can combine certain natural laws from these observations, from these experiments; natural laws in which, however, the human being with his physical corporeality is also harnessed. But the attempts made to go beyond the limits set by the sensory world by mere reason alone — as one also says, by philosophical thinking — always leave the unbiased person unsatisfied. The unbiased person feels: as soon as scientific thinking, as we are accustomed to it today, leaves the paths of sensory experience, experiment and observation, thinking left to its own devices enters into uncertainty. The dispute between philosophical systems testifies to the extent to which thinking left to its own devices enters into uncertainty. Anthroposophical research in particular makes it clear how this thinking, which we have in ordinary life and in ordinary, recognized science, not only binds itself to the sensory experience of the level-headed natural scientist out of habit or arbitrariness, but how it itself is dependent step by step on this sensory experience, so that it only has certainty when this external experience, this sensory experience, guides it.
