Gaw directs me to the Times obit of Leszek Kolakowski, which includes this summation of the philosopher’s views on the question of God:
Kolakowski offered a critical analysis of a wide range of arguments for religious beliefs. He sought to understand them through their historical, anthropological and cultural backgrounds. In Christianity, for example, he saw the development of God from a basis in early Greek philosophy of the One, later merged with the Jewish concept of a loving God. Thus he maintained a cultural and human conception of religion...
He also held that rational inquiry could never settle religious questions such as whether or not God exists….
His approach was, ultimately, unpalatable to both religious believers, whose faith he explained culturally, and scientists, whose knowledge he thought was ultimately based on faith.
Nobody knows nuffink. Perhaps good philosophy is the business of accepting this obvious truism but still finding stuff to say.
