Like pollen on a honeybee, flattery clings to the things you tell yourself.

Great quotation collections glean the millennia, distill essences, and battle for bragging rights about who’s bigger, who’s smarter, who’s best. Who-knows-who-said-what has a market, a history, and a hall of fame.

If you flatter yourself properly you will be better able to enjoy yourself. Stretch your joy so that others enjoy you too.

Quotations calcify into clichés.

Say what you want without saying it yourself: quote. Very useful, this, sometimes lovely, and versatile, too: big thoughts in small pieces, neatly wrapped and bundled in bulk, in different flavors for different tastes.

Quotations cause all kinds of trouble.

Maria Edgeworth grumbled against vandals who ruined immortal works by quoting the life out of them. "How far our literature may in future suffer from these blighting swarms, will best be conceived by a glance at what they have already withered and blasted of the favourite productions of our most popular poets." Shakespeare, Milton, and Dryden, scissored, patched, and frayed.
