1. Knowledge of Nature and Knowledge of the Mind

Another human power that is necessary for life in the most eminent sense, and which must not be broken for this ordinary life, just as little as the power of memory or recollection, is the power of love. Now, you all know how this power of love is bound to the human organism in ordinary life. It only comes into being at a particular age in the way that it has its special significance for social life, namely when a person reaches sexual maturity; before that it is only a kind of preparation — but this love is only a special case of what we call 'love' in general. Just as sexual love is bound to the human organism, so too is love in the ordinary sense bound to the organism. But just as knowledge can be released when memory breaks down, so love can be freed from the human organism when it is developed spiritually and soulfully through a special methodology. We must not, however, call in a trivial sense every manifestation of “platonic love”, which is nothing more than some vapour from the organism, but this love must be developed in the higher sense through human self-discipline, again through exercises as they are given in the writings mentioned. This love, which in ordinary life is not a power of knowledge, can be developed so that it transforms itself into the power of knowledge of true intuition. When we take into our own hands that to which we otherwise only surrender in life, that which actually educates us in life, in self-discipline, when we become, so to speak, more and more our own companion in our self-education in a strictly methodical way, then we arrive at making love a free force in the human being, in the human organization, and then it becomes a power of knowledge. And just as we arrive at self-knowledge by overcoming memory, so we arrive at supersensible knowledge by making love a cognitive activity in relation to the external world. There must be limits to our knowledge of the external world, otherwise we would not be able to develop love in us. If we were not separate from the external world, we could not be so separate from person to person as to develop love in social life. But when we have developed this love to higher knowledge, when we have it in a sufficiently healthy degree, and then develop it to the power of recognition, then we attain knowledge of the world just as we attain self-knowledge in the other way. And this knowledge of the world leads us to the knowledge of that world in which we only live between falling asleep and waking up, when we have no consciousness, when consciousness again fades away. We experience a state that is in some ways similar to the one between falling asleep and waking up, but we experience this state in full consciousness. There we experience a new external world. We do not experience an atomistic world, which underlies the external sense world, but we experience a spiritual world. To educate ourselves in love means to take the step into the true reality of the external world, into spiritual reality; into the reality that our soul absorbs every evening when we fall asleep, when our ordinary consciousness, which is still bound to the body, becomes unconscious because of the longing to return to the body that lies in the bed. When we ascend to a higher consciousness, we become acquainted with the world that consciously receives us when we pass through the gate of death. Thus, the two ends of our human life initially confront us scientifically. Much more will be further characterized in a subsequent lecture. Today, I have only set myself the task of showing how what can be inwardly cultivated in the soul through natural science must be expanded if true spiritual knowledge is to be attained through true spiritual science. Therefore, because the soul wants to educate itself, not in some amateurish, dilettantish way, but in strict methodology, if it wants to ascend from nature-knowledge to spirit-knowledge, therefore one may also believe: Whoever is able to judge from the full humanity what material natural knowledge gives us, and who is able to recognize that we strengthened through material knowledge, will also be able to find his way into the contemplation that seeks this strengthening of the ego on the other, the spiritual side, into which we fall asleep, dream, or which we encounter in pathological states, but which we can develop in a completely healthy way, in order to then advance to a spiritual knowledge of the world. Therefore, I believe that anyone who can fulfill the recognition of nature in the right way will also ascend to a spiritual recognition that is accessible to every human being, but especially to those educated in natural science. Therefore, I believe that the recognition of spiritual science will come precisely through the strengthening of the scientific spirit and the recognition of nature.
