Daniel Trilling, writing an introduction to the New Humanist magazine, tells us:
"... in our new-look quarterly format, we want to provide a space where people from different backgrounds, with different life experiences, can come together and discuss the kind of society we’d like to build. As Kenan Malik argues in his cover story for our Winter 2013 issue, age-old fears about “alien” cultures have been given a new lease of life by globalisation, under which the old political certainties have been eroded and identity politics have thrived. In Britain at least, the political consensus that “too much” diversity is a bad thing has become so stifling that dissenting voices are fast becoming marginalised."
Here we can see, in one paragraph, all that is wrong with rationalism (sic), immigration and diversity.
It supposes that there is only one "rational" view of things (in this respect Mr Trilling resembles Ayn Rand with her atheist objectivist certainties).
Note the patronising assumption that opposition to immigration and alien cultures is based on "fears".
Presumably it has not occurred to Daniel Trilling and his rationalist colleagues that opponents to immigration have looked at the issue calmly, intelligently, indeed rationally, and come to the conclusion that they do not want it (and that "not wanting immigration" is a democratic right that they can choose to have enforced).
Also note the breathtaking arrogance with which Mr Trilling describes his ambition: "...we want to provide a space where people from different backgrounds, with different life experiences, can come together and discuss the kind of society we’d like to build."
"The kind of society we'd like" has already been built Mr Trilling. It was constructed organically over the last one thousand five hundred years. The validity and desirability of this society can be gauged by the countless millions of people all over the world clamouring to come here.
Of course, humanists when they reject God do not become "rational" atheists. They simply substitute themselves for God, and place themselves at the centre of the universe. Thus Daniel Trilling's desire to play God and rebuild society.
