Every social revolution is preceded by, or brings with it, a change in the
perception of the world or a change in the perception of the possible or
both. Just as inevitably, these altered perceptions are first seen as ridiculous
nonsense or worse by the collective common sense of the time. . . .
The belief that slaves were not chattels to be bought and sold . . . but
were persons with full personal rights was not only . . . contrary to history
and the Bible, itwas economically upsetting and dangerous. . . . Yet
every one of these “ridiculous” perceptual changes altered the face and
the nature of our world. It is the “common sense” that gradually came to
be seen as ridiculous. —Carl Rogers (1977, p. 285)
I'm just reading this excellent article (
http://jhp.sagepub.com/cgi/content/abstract/45/1/106) by Prof Melanie Joy (psychology) who has studied the psychology of speciesism for several years. She conducts workshops to help activists advocate more effectively (gosh we need that!) and works towards integrating justice movements. She's been an animal/environmental/human rights activist for 15 years. She is writing a book on amimal advocacy.
