With intellectual ingenuity, proof can be furnished in support of the most radically opposing theories…
The intellectualism prevailing among men to-day is not capable of demonstrating the inner potentialities and values of anything. It can furnish proofs; but what is intellectually proved should not be regarded as of real value or efficacy in life. Men oppose one another in parties because the soundness of every party opinion — at any rate the main party opinions — can be proved with equal justification. Our intellect remains at the surface-layer of understanding and does not penetrate to the deeper layer where the truth actually lies.…
For that it is essential above all to realize that wallowing in abstractions, however loud the cry for the spirit, is not yet spiritual, not yet spirit! Vague, abstract chattering about the spirit must never be confused with the active search for the content of the spiritual world pursued in anthroposophical science.…
Purely intellectual allusion to the spirit leads nowhere.…
The picture presented to you by the mirror is you, but it has no reality at all. It is nothing but a reflection. All the intelligence within your soul, all the intellectual content, is only a mirror-image; it has no reality.…
Man is intelligent only because his body is there. And as little as you can touch yourself by stretching your hand towards your reflected image, as little can you lay hold of the spirit if you turn only to the intellectual — for the spirit is not there! …
The reason why intelligence is so seductive is that it yields a picture, a reflected picture of the spirit — but not the spirit itself.…
But if men are able to rouse themselves to take into their consciousness what we have been studying, if they are able so to guide it that humanity can freely confront the Ahrimanic influence, then, when Ahriman appears, men will acquire, precisely through him, the power to realize that, although the earth must enter inevitably into its decline, mankind is lifted above earthly existence through this very fact.
When a man has reached a certain age in physical life, his body begins to decline, but if he is sensible he makes no complaint, knowing that together with his soul he is approaching a life that does not run parallel with this physical decline. There lives in mankind something that is not bound up with the already prevailing decline of the physical earth but becomes more and more spiritual just because of this physical decline.
Let us learn to say frankly: Yes, the earth is in its decline, and human life, too, in respect of its physical manifestation; but just because it is so, let us muster the strength to draw into our civilization that element which, springing from mankind itself, will live on while the earth is in decline, as the immortal fruit of earth-evolution.
