Opposite

The opposite of black is white

The opposite of up is down

But isn't it right that the opposite of truth is not lies, but ignorance?

Because truth is genuine knowledge. Yet lies are knowledge too. Ignorance is empty of both. Ignorance is blank, almost child-like, at that stage when the questions start, the search for truth.

If lies and truth were opposing forces, I would think that we would not accept one in place of the other. Who would prefer lies over truth, right?

Yet we prefer lies and truth both, when compared to ignorance. When compared to knowing nothing at all, we will take anything in trade, won't we. We humans.

Because lies are not the opposite of truth. Ignorance is the opposite of truth.
