The only thing more dangerous than ignorance is the pretense of intelligent ignorance. The former is teachable; the latter is not.
It is never just disagreement but always intellectual dishonesty that is the apologist's worst enemy. And its apprentice is ignorance.
It is ignorance that is at times incomprehensible to the wise; for instance, he may not see 'the positive person' or 'the negative person' in a black and white way as many people do. A wise man may not understand it because, as a catalyst of wisdom, but not wise in his own eyes, even he can learn from and give back to fools. To think that an individual has absolutely nothing to offer to the table is counter-intuitively what the wise man considers to be 'the ignorance of hopelessness'.
The greater ignorance towards a country is not ignoring what its politicians have to say, it is ignoring what the inmates in its prisons have to say.
