Many errors, in truth, can be traced to this head, namely, that we do not apply names to things rightly.
Knowledge rests not upon truth alone, but upon error also.
It is difficult to know how to treat the errors of the age. If a man oppose them, he stands alone; if he surrender to them, they bring him neither joy nor credit.
It is as certain as it is strange that truth and error come from one and the same source. Thus it is that we are often not at liberty to do violence to error, because at the same time we do violence to truth.
Error is related to truth as sleep to waking.
But what after all are man’s truths? They are his irrefutable errors.[Was sind denn zuletzt die Wahrheiten des Menschen? – Es sind die unwiderlegbaren Irrthümer des Menschen.]
All error, not merely verbal, is a strong way of stating that the current truth is incomplete.
