This strange interior of the world (R. Wilhelm 1979)

Life, however, is the exact opposite of death, and the energy of life is neither visible nor within matter; life's energy differs essentially from all other forces. The secret of existence may very well be that in addition to forces active in matter, there is the mystery that these energies are forever redirected so as to bring about something new. Causality conditions their flow and ebb, and strict necessity conditions development. By understanding these energies, one can predict today what is to happen ten thousand years hence. But the unfolding, the folding asunder in time, is only one of the forms of appearance. It is not real, for each effect, each consequence, is contained in the cause.

And now the ring must be broken. But not broken so that at any point its laws would cease to be valid. Indeed, Europe's most important contribution to the knowledge of nature is probably its emphasis on causality, the sequence of cause and effect, and its universal validity. In effect, we have nowhere a point where this relationship could be rejected and where we could say: "This is a miracle. Here is empty space, where somehow something scientifically inaccessible is happening; where something disappears and something new, previously unconditioned, appears." But while causality is valid throughout the world of appearances, we find this world, and acting through it, something that is not subject to causality. It is valued, knows value, and creates values. This strange interior of the world - if we may designate this relationship so - is inseparably united with the exterior. One could not speak of it as the seed and of something else as the shell. Nature has neither seed nor shell; both inseparably interpenetrate one another, and yet there is an essential difference. This system of values, which is the basis of all the arts, is present together with the system of causality.

Here is an interesting phenomenon. It seems that a mechanical effect can take two directions in the organism: constructive or destructive. Causality does not give us the reason. For this is the neutral point, the point where causality enters the phenomenon. Whatever lies beyond phenomenon must always be inaccessible to science. However, we see that certain chemicals support and nourish the life of our bodies and maintain them. On the other hand, only a second later, without essential changes in the body's chemical composition, we may find that this same causality, acting in reverse, results in the gradual decomposition and decay of the body. It is the same causality and the same substances; once working this way, and once working that; both activities can be scientifically examined. Indeed, we would be superstitious were we to assume that living organism are less accessible to science than dead organisms. On the contrary, the opportunity and duty of science is to investigate to an even greater extent the complicated constructional texture customarily designated as life.
