Quote from ‘The Rationale of Reason’
…that circumstance is Real which is as it is whether one thinks that it is so, or not. That object is Real of which whatever is true or is truly said, is so, whether you or I or any person or persons think that it is so, or not, – unless, indeed, the predicate in question (i.e. that which is said of the object,) be, of its very meaning, dependent upon what one thinks of it.
MS [R] 659:32-3
