Observe the course of the year. It takes its course in such a way that there are days of rain and days without rain. As to the rain, the modern physicist investigates practically no more than the mere fact that when it rains, more water falls upon the Earth than when it does not rain. For him, the water is an abstract substance composed of hydrogen and oxygen. True, if you decompose water by electrolysis, it will fall into two substances, of which the one behaves in such and such a way, and the other in another way. But that does not yet tell us anything complete about water itself. Water contains far, far more than what emerges from it chemically, in this process, as oxygen and hydrogen. (Steiner 2007:13)
