Within.

The coming peril is the intellectual, educational, psychological and artistic overproduction, which, equally with economic overproduction, threatens the wellbeing of contemporary civilisation. People are inundated, blinded, deafened, and mentally paralysed by a flood of vulgar and tasteless externals, leaving them no time for leisure, thought, or creation from within themselves.

G.K. Chesterton
