Context: The real intent of my writing is not to say, you must think in this way. The real intent is: here are some of the many important facets of this extraordinary Kosmos; have you thought about including them in your own worldview? My work is an attempt to make room in the Kosmos for all of the dimensions, levels, domains, waves, memes, modes, individuals, cultures, and so on ad infinitum. I have one major rule: Everybody is right. More specifically, everybody — including me — has some important pieces of truth, and all of those pieces need to be honored, cherished, and included in a more gracious, spacious, and compassionate embrace. To Freudians I say, Have you looked at Buddhism? To Buddhists I say, Have you studied Freud? To liberals I say, Have you thought about how important some conservative ideas are? To conservatives I say, Can you perhaps include a more liberal perspective? And so on, and so on, and so on... At no point I have ever said: Freud is wrong, Buddha is wrong, liberals are wrong, conservatives are wrong. I have only suggested that they are true but partial. My critical writings have never attacked the central beliefs of any discipline, only the claims that the particular discipline has the only truth — and on those grounds I have often been harsh. But every approach, I honestly believe, is essentially true but partial, true but partial, true but partial.
And on my own tombstone, I dearly hope that someday they will write: He was true but partial...
