Accordingly, the power that thought exercises is fundamentally different from the physical power of association, or even of custom. In the case of thought there is an insistence upon a consistent and related whole which, even though externally insignificant, produces most powerful effects. If contradictions exist in our world of thought and condition of life, they may become intolerable, and the desire to remove them lead to the emergence of impetuous movements. If, on the other hand, we recognise that certain things which formerly seemed to be unrelated, even though they existed side by side, are really inwardly related; or if, again, an assertion involves a consequence that has not hitherto been deduced, then the demand, that these things shall be unified and this consequence developed, is capable of breaking down even the strongest opposition. In this matter an invisible is capable of more than a visible power. Of course, thought in isolation has not such a power; it acquires it only through its relation to a wider life and in championing the cause of that life. For thought is wont to defend the life of the individual, of a people, a historical situation of humanity, on the one hand from an abundance of inconsistencies, and on the other from dissolution and incompleteness, without any conflict growing out of it. Life as we experience it immediately is anything but a regular logic of the schools. In itself simple perception of the fact that an inconsistency exists, or that ideas which have been regarded as valid require further development, need not arouse the feeling of man and lead him to assert his activity; he can acquiesce, and leave the condition of things unaltered; he can voluntarily resign himself to the inconsistencies and incompleteness. But, nevertheless, there is a point at which this condition of inconsistency can be endured no longer, at which to transcend it becomes the dominant task of life. This point is reached when the confusion is no longer something external to us which we contemplate, but enters into the substance of our life, so that the inconsistency becomes a division, and an attitude of inconsequence towards it a limitation of our own being. The solving of the problem then becomes an essential part of our spiritual preservation. And in that it commands the whole energy and passion of such preservation it can do that of which thought, with its necessity, is not in itself capable, it can rouse our whole life to activity and break down even the strongest opposition. It is from the inner presence of a determining and moulding process of life that thought itself first obtains a characteristic form, and is able to impress it upon things, and so subject them to itself. A spiritual self-preservation of this kind is fundamentally different from all physical self-preservation: for the former, it is not a matter of the self asserting its place in the co-existence of things, but of becoming an independent inward nature,
