It is right that we be concerned with the scientific probity of metaphysics.

Metaphysics is a science.

But a science is exact to the extent that its method measures up to and is adequate to its object.

On a grassroots level we say that man can touch more than he can grasp.

Contemplation and wisdom are highest achievements and man is not totally at home with them.

The dynamic element in my philosophy, taken as a whole, can be seen as an obstinate and untiring battle against the spirit of abstraction.
