"Why I Am for Humphrey," The New Republic, June 8, 1968.

Excerpt:

Mr. Humphrey, in contrast, seems to me to be capable of moulding and leading the right kind of majority–one that does not wish to repudiate American traditions (and, yes, even the “American way of life”) but is nevertheless genuinely willing to adapt these traditions to the exigencies of present and future circumstances. It might be said, in rejoinder, that such adaptation might be insufficiently swift and radical. To which I can only reply (a) that this is indeed a possible danger, and (b) that the only real alternative is an Administration that will not be particularly interested in adapting at all.
