This is a tricky one. I wouldn’t be doing it if it were a no-brainer. I consider my brain to be one of my favorite organs. But thinking isn’t all the brain does, and sometimes, it’s not even the organ engaged in thinking. Thinking is just something I do before I do most other things, and it’s a practice that serves me well. The chances of doing something right is drastically increased when the brain is involved in the process. My consideration is that thinking is ideally involved in the process of doing, and in itself a form of doing. What precedes thinking, as it should be primary response, is the need. A need arises from our being, which is embedded in our environment. The reason for thinking, moving and doing is our constant being as consuming entities. This constant metabolizing of our environment requires us to extract the consumable resources from said environment, which is an action. There really is no sense in pondering which of those verbs has more meaning for anyone. Sum, ergo cogito; cogito, ergo ago; ago, ergo sum.
