And haven't I told you that what you mistake for madness is but over-acuteness of the senses.E.A.Poe Hi folks, I've read this following citation from Edgar Allan Poe: "And haven't I told you that what you mistake for madness is but over-acuteness of the senses." I've been trying to understand what "but" in this context means. Does it in this context mean "only" or does it have another meaning? Thank you,
