Truth is within ourselves; it takes no rise From outward things, whate'er you may believe. There is an inmost centre in us all, Where truth abides in fulness; and around, Wall upon wall, the gross flesh hems it in, This perfect, clear perception-which is truth. A baffling and perverting carnal mesh Binds it, and makes all error: and to know Rather consists in opening out a way Whence the imprisoned splendour may escape, Than in effecting entry for a light Supposed to be without.
