From our own experiences, we cannot possibly know what it is like to be a bat. Although we may be able to relate to certain sensations such as fear or hunger, we do not have the capacity to understand what it is like for a bat to experience these phenomena. Nagel says that the idea of imagining what it is like to really be a bat is beyond our ability to comprehend.
