Abstract
Fodor defines epistemic boundedness as a condition wherein there are epistemi‐cally significant constraints on the beliefs that a mind is capable of entertaining. He discusses a type of (epistemic) boundedness wherein a hypothesis cannot be entertained because it is inexpressible in terms of the mind's stock of concepts. In addition to this semantic boundedness, I describe a number of different sources of boundedness having to do with syntactic, abductive, and implementational limitations. I also discuss the similarities and differences between individual and social limitations on our epistemic possibilities.
