Truth is within ourselves; it takes no rise
From outward things, whate’er you may believe.
There is an inmost center in us all,
Where truth abides in fullness; 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 of opening out a way
Whence the imprisoned splendor may escape,
Than in effecting entry for a light
Supposed to be without. Robert Browning
