Stuk 133 - Letter from Augustus De Morgan

7 Camden Street, N.W. - Thinks that all the systems of general logic hitherto have been too mathematical and that William Hamilton Is 'the most ultra-mathematical of the too mathematical logicians', De Morgan 'cannot help laughing - but so it is. And this conclusion has been gradually evolved by symbolic thought'. Asks for help with names for logical entities, for example if A is essential to B, what is B to A - is there something better than 'Dependent'? He gives other examples of where he needs words to describe certain relationships.
