The quest for certainty, both in philosophy and law, offers ample evidence of philosophical failures.

The polarized politics of our time, joined with an appetite for pigeonholing, exert pressure on everyone to categorize themselves. Sometimes people declare themselves for "isms" that they have not plumbed. An example in point is conservatism. The politicians who now travel under the banner of "conservatism" happen to espouse views and methods that are incompatible with the philosophy bearing that name.

This includes a cautious disposition to welcome expert reasoning about economic policy, reasoning of the sort desperately needed for recovery. When the details of this are made clear, so are voters' alternatives in the forthcoming election.
