     Let us return to the hypothesis that generated the paradox: All nonblack things are nonravens.

   • 2007, Marc Lange, Philosophy of science: an anthology

     Hempel remarks that if we know that we are indoors, and so that the object under examination is a nonraven, then we have no need to check whether it is nonblack (ie, to do ornithology indoors) in order for our report of that object to logically entail H's development.

• Used in philosophical discussions of Hempel's paradox.
