Paracelsus
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, the 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 splendor may escape, than in effecting entry for a light supposed to be without.
-Robert Browning
