Even if we are pessimistic about the chances of changing our political culture to make it more reasoned, we have little choice but to try. In politic… - Julian Baggini

Really good philosophising requires something more than a razor-sharp brain, something that is sometimes called subtlety of mind, a philosophical sensibility or insight. I call it judgement, which I define somewhat cumbersomely as as a cognitive faculty required to reach conclusions or form theories, the truth or falsity of which cannot be determined by an appeal to facts and/or logic alone. There are numerous examples of this, but perhaps the clearest comes from moral philosophy.

Only our most intimate friends know our deepest flaws, and in the same way the greatest skeptics about reason should be those who seek to defend it. If we do not debunk the grandiose myths of reason then its enemies will do so far more destructively. My positive case for rationality therefore requires taking us through four key myths of rationality, all of which can be traced back to Plato. These myths are: that reason is purely objective and requires no subjective judgement; that it can and should take the role of our chief guide, the charioteer of the soul; that it can furnish us with the fundamental reasons for action; and that we can build society on perfectly rational principles.

Philosophers understandably focus on the nature of reason itself. However, in order for reason to flourish, it needs to be practised in the right environment. And that is sadly often lacking in the very places where reason is held in the highest esteem.
