Truth is within ourselves; it takes no rise from
outward things, what e’er you may believe.
There is an inmost center in us all,
Where truth abides in fullness . . . 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 "Paracelsus 13"
