By deepening our contemplation of cosmic secrets — with which the secrets of human existence are connected — we shall learn to understand the nature of the man standing before us; we shall learn to silence our preconceptions and to feel and recognise the true qualities of the individual in question. The most important light that Spiritual Science can give will be the light it throws upon the human soul. Thereby sound social feelings, also those feelings of love which ought to prevail between human beings, will make their way into the world as a fruit of true spiritual knowledge. We shall recognise that our grasp of spiritual knowledge alone can help this fruit to grow and thrive.
When Schopenhauer said: “To preach morality is easy; to establish morality is difficult”, he was giving expression to true insight. After all, it is not so very difficult to discover moral principles, neither is it difficult to preach morality. But to quicken the human soul at the point where spiritual knowledge can germinate and develop into true morality capable of sustaining life — that is what matters. Our attitude to spiritual knowledge can also establish within us the seeds of a truly human morality of the future. The morality of the future will either be built on the foundations of spiritual knowledge — or it will not be built at all!
