The common theory of property starts from the premiss, that all men have the right to property, and draws the conclusion, that, therefore, some men have the right to monopolize it.
"Contemporary Socialism"
John Rae
We should only have to assume as a premiss the definition of a nonentity; or rather of a name which has no entity corresponding to it.
"A System Of Logic, Ratiocinative And Inductive (Vol. 1 of 2)"
John Stuart Mill
But when the conclusion is a proposition concerning a Thing, the postulate involved in the definition which stands as the apparent premiss, is the existence of a Thing conformable to the definition, and not merely of an idea conformable to it.
