Abstract
The paper argues a certain parallelism between the perception and the conception of real-world objects. Just as the former is always incomplete, perspectival, and error-prone, so is the latter. We can never claim ultimate correctness for our conception of things. This fact is crucial for communication, because if our own conceptions were claimed as definitive, then we could never be secure in our confidence that we are in communicative touch with one another regarding a common, shared object of communication.
