There are many places where Peirce uses the word object in the full pragmatic sense, so much so that it demands a very selective attention not to remark them. I cited a couple at the top of this discussion but perhaps the most critical locution for the sake of pragmatism is stated here:
Consider what effects that might conceivably have practical bearings you conceive the objects of your conception to have. Then, your conception of those effects is the whole of your conception of the object. (CP 5.438).
