Abstract

There may in general be said to be two ways in which progress may be made in the understanding and towards the solution of a problem. The one is that of the continual development of it in the form originally given to it, by confirming this and rejecting that point in the light of fresh evidence, by clarification of concepts, and by detecting and resolving ambiguities and inconsistencies. Here it is assumed that the standpoint from which the problem has been approached is relevant and adequate. The other is entered upon when an “impasse” has been reached which can only be avoided by the realization that the original question was asked in a way which was either partially or wholly false or misleading. This is the more radical way of partial or total reformulation of the problem to be solved
