Condillac

“No matter how high we climb or how low we descend, we never escape our sensations. We never disembark from ourselves. We never attain another existence unless we other ourselves by actively, vividly imagining who we are. The true landscapes are those that we ourselves create since, being their gods, we see them as they truly are, which is however we created them. None of the four corners of the world is the one that interests me and that I can truly see; it's the fifth corner that I travel in, and it belongs to me.”
