John Gray om det sekuläras kristna rötter

“Secular thinking is a legacy of Christianity and has no meaning except in a context of monotheism […] Post-Christian secular societies are formed by the beliefs they reject, whereas a society that had truly left Christianity behind would lack the concepts that shaped secular thought."
