As for the Prager example, it is certainly true that some environmentalists are extremists.&#0160; But others are not.&#0160; So Prager&#39;s assertion is not even true.&#0160; Even if every environmentalist were an extremist, however, it would still not be true <em>by definition<\/em> that that is so.&#0160; <em>By definition<\/em>, what is true by definition is true; but what is true need not be true by definition.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: georgia,palatino;\">So what game is Prager playing?&#0160; Is he using &#39;by definition&#39; as an intensifier?&#0160;&#0160; Is he purporting to make a factual claim to the effect that all environmentalists are extremists and then underlining (as it were) the claim by the use of &#39;by definition&#39;?&#0160; Or is he assigning by stipulation his own idiosyncratic meaning to &#39;environmentalist&#39;?&#0160; Is he serving notice that &#39;extremist&#39; is part of the very meaning of &#39;environmentalist&#39;
