Abstract

In 1929, Wittgenstein reconsidered the vexing color-Incompatibility problem: explaining how and why more than one color cannot be at a single time and place. He continued discussing the problem in 1930 and later. He offered solutions in the "tractatus", In 1929 and in 1930. Are the solutions the same? clearly not, Because the 1929 solution differs from his earlier one. However, I argue that the 1930 solution is substantially identical with that of 1929 and that the 1929-30 solution is continuous with the "tractatus" as well as some later doctrines. Therefore 1929-30 marks a period of intellectual ferment rather than massive abandonment of his earlier views
