You can see with your tongue if your eyes are gone, *
For you see with your brain, not your senses.
It matters not where the signals come from,
Whether it’s taste buds or lenses.
The objects out there, when seen, heard, or tasted
get known to your brain by patterns of feel.
For no matter what some philosophers say,
the objects out there are REAL.

* This has been done by physicians for some blind patients.
