Brian Eno on Culture and Karl Popper’s Philosophy of Science

From Brian Eno’s A Year with Swollen Appendices:

In [Karl] Popper’s ‘World 3’ [from In Search of a Better World] he includes art and literature etc., but is in no doubt that science is the important part. He also says, ‘In the hierarchy of controls, the self is not the highest control centre since it is, in its turn, plastically controlled by World 3 theories. [Not sure where his quote ends, perhaps here.] But the whole body of ‘theories’ which constitutes people’s sense of what is morally and socially and personally acceptable is actually arrived at by a grindingly detailed process of consensus – not proof or disproof. The strong voices in this process may include philosophers and scientists but also artists and soap-opera directors and ideologues and advertisers. So what Popper seems to be saying is that the valuable (as opposed to the most effective) voices are those of science. But couldn’t you invert this and say that, since the most heard voices are those of art and soap, then a sensible policy would be to improve their quality, to dignify them by serious critical attention (that’s to say, with a type of criticism which tries to ask, ‘What is the effect of this work?’ – that asks questions outside art), to require that they do better for us?
