## ABSTRACT

ACCORDING to Mr. S. N. Gupta,1 the first thing that every student of Hindu logic has to learn when he is said to begin the study of inference is that " all H is S " is not always equivalent to " No H is not S." " The latter proposition is an absurdity when S is Kebaldnvayi, i.e. covers the whole sphere of thought and existence. . . . ' Knowable ' and ' Nameable ' are among the examples of Kebaldnvayi terms. If you say there is a thing not-knowable, how do you know it ? If you say there is a thing not-nameable, you must point that out, i.e. somehow name it. Thus you contradict yourself."
