Abstemius's Fables (Sir Roger L'Estrange)
286. (Abstemius 34) The Frogs and Tortoises.
As a Company of Frogs were trifling and playing up and down in a Meadow, some Tortoises, that look'd on, were mightily troubled that they could not do so too: But taking notice a while after, how these Frogs were pick'd up, and destroy'd by Birds and Fishes: Well (says one of 'em) 'tis better to live Dull and Heavy, than to die Light and Nimble.
Every Part and Creature of the Universe has its proper Place Station, and Faculties assign'd; and to wish it otherwise, were to find fault with Providence.
