A Challenge

Extract

In recent issues of the Journal of Philosophy John Dewey and Arthur Bentley have been making an attack on certain logical positivists and other logicians on the ground, of all things, that they display amazing contempt for clear and consistent definition of the terms they use. That logicians, whose business it is to define consistency, should themselves be inconsistent in the use of their basic terms is not really so surprising. It may merely prove them to be human, the victims of a simple failure to practice what they preach. If this were the case, the situation would not be so bad, for who better than a drunkard knows the evils of drink? And yet it is equally human to require preacher to be practitioner as well. So that the spankings which Bentley and Dewey are currently administering to Carnap, Cohen, Nagel, Ducasse, Lewis and Morris are quite in order. In fact in the case of the logical positivists they are long overdue. Carnap, particularly, has long outraged patience as well as common sense with rambling verbal analysis of the meaning of terms used in the exposition of logical positivism.
