“In argument similes are like songs in love; they describe much, but prove nothing.”

“The strongest argument proves nothing so long as the conclusions are not verified by experience.”
[H]aec vocatur scientia experimentalis, quae negligit argumenta, quoniam non certificant, quantumcunque sint fortia, nisi simul adsit experientia conclusionis. Et ideo haec docet experiri conclusiones nobiles omnium scientiarum, quae in aliis scientiis aut probantur per argumenta, aut investigantur per experientias naturales et imperfectas...

“A metaphor is like a simile.”

“The argument goes something like this: "I refuse to prove that I exist," says God, "for proof denies faith, and without faith I am nothing.”

“4384. That, which proves too much, proves nothing.”

“Reading the Socratic dialogues one has the feeling: what a frightful waste of time! What's the point of these arguments that prove nothing and clarify nothing?”

“Oh, what a love it was, utterly free, unique, like nothing else on earth! Their thoughts were like other people's songs.”

“How can I describe how much I love you?
Is it even possible to describe a love like that? I don’t know, but as I
sit here with pen in hand, I know that I have to try.”

“Much suspected by me,
Nothing proved can be,
Quoth Elizabeth prisoner.”

“A song nobody likes is a sad thing. But a love song nobody likes is hardly a thing at all.”
