Abstract

In Physical Theory Mr. Lenzen writes, “Thus the concept of thing is the concept of a class of aspects which are in the past, present, or future for several minds.” Again, in Mind and the World-Order, Mr. Lewis defines “thing” as “… a complex of properties or qualities, recognizable by some uniformity of appearance.” Without questioning the metaphysics implied in these two definitions of “thing” I shall accept them as quite compatible and as useful in defining the rôle of experience in the construction of scientific objects. If in “Pragmatism and Metaphysics” Mr. Morris has not established proof of the existence of objects independent of any and all experience of them, he certainly has shown conclusively that the possibility of experiencing objects is independent of any and all observers.
