Quote from ‘Note (Notes on Art. III) [R]’

I will now give an idea of what I mean by likely or verisimilar. [—] I call that theory likely which is not yet proved but is supported by such evidence, that if the rest of the conceivably possible evidence should turn out upon examination to be of a similar character, the theory would be conclusively proved. Strictly speaking, matters of fact never can be demonstrably proved, since it will always remain conceivable that there should be some mistake about it.
