" We must remember that we are living in an age in which the ground is shifting and the foundations are shaking. I cannot answer for other times and places. Perhaps it has always been so. We know it is true today. In these circumstances, we have all reason to be insecure. When the ultimate basis of our world is in question, we run to different holes in the ground; we scurry into roles, statuses, identities, interpersonal relations. We attempt to live in castles that can only be in the air, because there is no firm ground in the social cosmos on which to build."
"Sanity today appears to rest very largely on a capacity to adapt to the external world — the interpersonal world, and the realm of human collectivities. As this external human world is almost completely and totally estranged from the inner, any personal direct awareness of the inner world already entails grave risks."
