Analogies & comparisons Analogy: the property of cleverness is the same

Analogies & comparisons

Analogy: the property of cleverness is the same as

height, sex, etc.
Consistency: what is true of height, sex, eye colour should be true of cleverness. If x is like y in every respect, then everything that’s true of x should be true of y. But – not all analogies are good analogies…. Is this one a good one?
NB: In arguments based on analogy, we are usually expected to accept the premise, on which the analogy is based. Are we happy to accept the premise that we should not praise someone for their physical attributes?

“We shouldn’t praise people who are clever, any more than we would praise someone for being born one or other sex, or being tall or having brown eyes…”
