Light is meaningful only in relation to darkness and truth presupposes error. It is these mingled opposites which people our life which make it pungent intoxicating. We only exist in terms of this conflict in the zone where black and white clash.

There is no original truth only original error.

I see that the path of progress has never taken a straight line but has always been a zigzag course amid the conflicting forces of right and wrong truth and error justice and injustice cruelty and mercy.

Books and all forms of writing are terror to those who wish to suppress the truth.

Be calm in arguing for fierceness makes error a fault and truth discourtesy.

An error is the more dangerous in proportion to the degree of truth which it contains.

There are sadistic scientists who hurry to hunt down errors instead of establishing the truth.

The man who cannot endure to have his errors and shortcomings brought to the surface and made known but tries to hide them is unfit to walk the highway of truth.

It is one thing to show a man that he is in an error and another to put him in possession of the truth.

There is no such source of error as the pursuit of truth.
