Analogies, like metaphors, require that things not be identical. But have some relevant similarities. And so, if you’re arguing that because X is like Y, we should treat X-cases like Y-case… you’re also committing to the thought that Xs are not Ys. Just, well, like Ys. That’s it. But if you said, “Cases of X literally are cases of Y,” that’s a different claim.
Dennis Prager at Townhall argues that entitlements are like drugs and alchohol, because they create addictions to them. Especially when they are given for free and in large quantities. And then as a consequence, they create dependent and entitled populations. And he then concludes:
In this sense, the left in every country — in America, the Democratic Party — should literally be regarded as a drug dealer. Virtually every American given a free benefit becomes an addict who relies more and more on his dealer, which is exactly what the left seeks.
What’s funny is that Prager’s argument is no longer about what entitlements do to the people who are offered them, his line is about what entitlements do to the people who offer them. But, of course, is he really saying of those who hold that there should be food stamps that they are to be treated literally like drug dealers?
Of course, the point is that when folks get carried away with their analogies, they forget that they aren’t identities. Oh, and the other problem is that maybe Prager’s been infected by the widespread use of ‘literally’ as an emphatic device.
