In René Descartes’ famous Discourse on Method, he summarizes the proof of his own existence with the dictum Cogito, ergo sum(I think, therefore I am). As an answer to someone doubting their own existence, it’s pretty OK (despite the tradition of philosophical criticism which has found various flaws with the line of reasoning itself). The interesting thing about the Cogito to me, though, is not whether it technically works as a philosophical argument, but rather the fact that the particular verb chosen is cogitare. It makes sense in the context of the argument, where the only thing we are supposed to assume is the activity of thinking itself. But there is a deeper move being made here: the elevation of thought as the quintessential or bedrock activity of human existence. In reality, any verb will do: I love, therefore I am. I dance, therefore I am. I sneeze, therefore I am. For Descartes, the only one of these that we cannot ultimately doubt takes place is the act of thinking. Typical philosopher!
