I've just started reading Peter Watson's voluminous history of 20th century thought, 'A Terrible Beauty', and already, in the introduction, Watson has said something which made me pause for thought:
The arts and humanities, it seems to me, have been to an extent overwhelmed and overtaken by the sciences in the twentieth century, in a way quite unlike anything that happened in the nineteenth century or before…The arts and humanities have always reflected the society they are part of, but over the last one hundred years, they have spoken with less and less confidence…Put simply, artists have avoided engagement with most…sciences. One of the consequences of this…is the rise of what John Brockman calls 'the third culture'…For Brockman the third culture consists of a new kind of philosophy, a natural philosophy of man's place in the world, in the universe, written predominantly by physicists and biologists, people best placed now to make such assessments.
I think this is spot-on. For the majority of the population in a Western country today, culture means popular culture, which means a source of entertainment. If you're interested in ultimate questions, then you consult what scientists have to say.
