encomiast

To charge all unmerited praise with the guilt of flattery, and to suppose that the encomiast always knows and feels the falsehood of his assertions, issurely to discover great ignorance of human nature and human life. In determinations depending not on rules, but on experience and comparison, judgement is always to some degree subject to affection.Very near to admiration is the wish to admire.

—Johnson, Samuel known as Dr Johnson
