I can't remember where I found this, but I posted it in the Deleuze thread a while back and just stumbled across it again;
"For Bergson, the quality of a thing is not separate from its place in time: there is no way to separate them. This includes human subjectivity. Bergson's notion is that by abstracting human qualities we completely miss their actual pragmatic intent and functioning. Time is a component of becoming. Nothing comes into being without time elapsing. The one constant of time elapsing is that it perpetuates continuous change. So an acorn is never a static acorn, it is also, somewhere along its timeline, a sprout, a fully grown tree, a decaying log. So in this sense, an acorn differs-in-itself. It's latent potentiality of becoming, it's radical differentiation from its current form, is already present within it."
