Abstract

THIS ARTICLE CLARIFIES A DISTINCTION MADE BY ME ELSEWHERE BETWEEN PRIMARY AND SECONDARY TESTS FOR THE APPLICATION OF A CONCEPT. IF THE PRIMARY TESTS ARE SATISFIED, THEN OF LOGICAL NECESSITY THE CONCEPT APPLIES, BUT SATISFACTION OF THE SECONDARY TESTS IS ONLY GOOD EMPIRICAL EVIDENCE FOR THE APPLICABILITY OF THE CONCEPT. THIS ARTICLE IS A REPLY TO ONE BY SLOTE (’A GENERAL SOLUTION TO GOODMAN’S RIDDLE?’ ANALYSIS, DECEMBER 1968) CHALLENGING MY EARLIER USE OF THIS DISTINCTION (’GRUE’ ANALYSIS, MARCH 1968) TO PROVIDE A SOLUTION TO GOODMAN’S RIDDLE.
