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 is perfect, clear perception-which is truth.
Robert Browning (1812-1882)
So we should not travel too far. Many of our wise sages have said the same, Socrates referred to education as withdawing wisdom from within. We read John(7:38) and it says, "from within...shall flow rivers of living water".
