We animals don't give plants nearly enough credit. When we want to dismiss a fellow human as ineffectual or superfluous, we call him a "potted plant." A "vegetable" is how we refer to a person reduced to utter helplessness, having lost most of the essential tools for getting along in life. Yet plants get along in life just fine, thank you, and did so for millions of years before we came along. True, they lack such abilities as locomotion, the command of tools and fire, the miracles of consciousness and language. To animals like ourselves, these are the tools for living we deem the most "advanced," which is not at all surprising, since they have been the shining destinations of our evolutionary journey thus far. But the next time you're tempted to celebrate human consciousness as the pinnacle of evolution, stop to consider where you got that idea. Human consciousness. Not exactly an objective source.
