"The point is, that every piece of art changes your whole perception of the rest of the world for the rest of your life. And it's not a joke! And if it doesn't, then it's not art, it's a commodity."

- Lawrence Weiner responding to a question from Liam Gillick in "Between Artists"

pg20

This is completely true.Obviously, some pieces of art affect us more than others, but they 100% change our perception of the world whether we realize it or not; at the very least you will remember that you've seen the piece previously. Every time after the initional veiwing you will have a sense of familiarity towards it even if you thought it sucked. It's quit wonderful that our minds work that way; an image can trigger a memory and emotions with a glance.
