“If you're a twofisted, spineless progressive (a mighty fashionable stance nowadays) Offissa Pupp, who forcefully asserts the will of socalled society, becomes a cosmic angel; while Ignatz Mouse, who forcefully defies society's socalled will by asserting his authentic own, becomes a demon of anarchy and a fiend of chaos. But if—whisper it—you're a 100% hidebound reactionary, the foot's in the other shoe. Ignatz Mouse then stands forth as a hero, pluckily struggling to keep the flag of free will flying; while Offissa Pupp assumes the monstrous mien of a Goliath, satanically bullying a tiny but indomitable David. Well, let's flip the coin—so: and lo! Offissa Pupp comes up. That makes Ignatz Mouse "tails."”
Now we have a hero whose heart has gone to his head and a villain whose head has gone to his heart.

“4678. The Mountains have brought forth a Mouse.”
Introductio ad prudentiam: Part II (1727), Gnomologia (1732)

“The mountains will be in labor, and a ridiculous mouse will be brought forth.”
Parturient montes, nascetur ridiculus mus.
Source: Ars Poetica, or The Epistle to the Pisones (c. 18 BC), Line 139. Horace is hereby poking fun at heroic labours producing meager results; his line is also an allusion to one of Æsop's fables, The Mountain in Labour. The title to Shakespeare's play Much Ado About Nothing expresses a similar sentiment.

Context: All these years, he thought, dreaming about a companion. Now I meet one and the first thing I do is distrust her, treat her crudely and impatiently.
And yet there was really nothing else he could do. He had accepted too long the proposition that he was the only normal person left. It didn’t matter that she looked normal. He’d seen too many of them lying in their coma that looked as healthy as she. They weren’t, though, and he knew it. The simple fact that she had been walking in the sunlight wasn’t enough to tip the scales on the side of trusting acceptance. He had doubted too long. His concept of the society had become ironbound. It was almost impossible for him to believe that there were others like him. And, after the first shock had diminished, all the dogma of his long years alone had asserted itself.
