ABSTRACT
IN order to illustrate the contention that at times two sense-data must be really different even though the percipient finds no difference between them, Mr. Bertrand Russell has adduced a state of affairs which is used in some quarters to support arguments to conclusions that exact resemblance is a delusion or, at least, a very doubtful question. “It would be easy to find three stuffs of such closely similar shades that no difference could be perceived between the first and second, nor yet between the second and third, while yet the first and third would be distinguishable. In such a case, the second shade cannot be the same as the first, or it would be distinguishable from the third; nor the same as the third, or it would be distinguishable from the first. It must therefore, though indistiguishable from both, be really intermediate between them.” (1)
