TPF Quote Cabinet "Our knowledge being so narrow, as I have shown, it will perhaps give us some light into the present state of our minds if we look a little into the dark side, and take a view of our ignorance, which being infinitely larger than our knowledge may serve much to the quieting of disputes, and improvement of useful knowledge...
He that knows anything, knows this, in the first place, that he need not see long for instances of his ignorance...
The clearest and most enlarged understandings of thinking men find themselves puzzled and at a loss in every particle of matter... all the simple ideas we have are confined... to those we receive from corporeal objects by sensation...
But how much these few and narrow inlets are disproportionate to the vast whole extent of all beings, will not be hard to persuade those who are not so foolish as to think their span the measure of all things...
But to say and think there are no such, because we conceive nothing of them, is no better an argument than if a blind man should be positive in it, that there was no such thing as sight and colors, because he had no manner of idea of any such thing, nor could by any means frame to himself any notions about seeing.
The ignorance and the darkness that is in us no more hinders nor confines our knowledge that is in others, than the blindness of a mole is an argument against the quicksightedness of an eagle."
