"I define thinking as paying attention to everything that is not oneself, or paying attention to oneself as if one were not oneself. Because of the misunderstandings this causes, I tend to use “being attentive” instead of “thinking,” and ‘attention’ instead of “thought.” One of the benefits would be to leave “thought” in its current usage. The idea of effort connected with it would be well explained by the concept of attention that is implicit in it. I then define idea as the gap between us and things. I am taken aback when I hear people say that ideas and things are identical. It is the power of this gap that defines the ability to think."
