A convenient mechanism

"'The truth,' Peta smiled, 'is that there is no truth. Life is just a series of coincidences, accidents and random urges which we carefully forge-- for our own sick reasons-- into a convenient design. Everything is arbitrary. Only art exists to make the arbitrary congeal. No memory or God or love, even. Only art. The truth is simply am idea an idea, a structure which we employ-- in very small doses-- to render life bearable. It's just a convenient mechanism, Kane, that's all." --from Darkmans by Nicola Barker
