The use of words was described as the central problem facing today's scientific philosopher by Max Black, professor of Philosophy at Cornell, last night in the first of a series of discussions presented by the Institute for the Unity of Science.

Speaking to an overflow crowd in the lecture room of the Institute of Geographical Exploration, Black said, "a great deal of improvement is needed in the clarification of terms."

Black saw two major difficulties facing today's scientist in his attempt to clarify. Primary was the problem of the difference between intuitive knowledge and logical knowledge.

A second major problem centers about the "linking of high level scientific concepts with low-level over-simplified words," according to Black.
