Richard Whately Quote

The easiest and most popular way of practically refuting... any Fallacy is, by bringing forward a parallel case, where it leads to a manifest absurdity. A metaphysical objection may still be urged against many cases in which we thus reason from calculation of chances; an objection not likely indeed practically to influence any one, but which may afford the Sophist a triumph over those who are unable to find a solution.
