17895	Combining two distinct assertions does not necessarily lead to a single 'complex proposition' [Mill]
	Full Idea: In 'Caesar is dead, and Brutus is alive' ...there are here two distinct assertions; and we might as well call a street a complex house, as these two propositions a complex proposition.
	From: John Stuart Mill (System of Logic [1843], 1.04.3)
	A reaction: Arthur Prior, in his article on 'tonk', cites this to claim that the mere account of the and-introduction rule does not guarantee the existence of any conjunctive proposition that can result from it. Mill says you are adding a third proposition.
