Folly is either related to, or identical with, the family of Lies, for in both cases it needs many to support one.

[Excusar una impertinencia con otra mayor es de casta de mentira, o esta lo es de necedad, que para sustentarse una necesita de muchas.]

Baltasar Gracián y Morales (1601-1658) Spanish Jesuit priest, writer, philosopher

Foppishness is of the race of Lying, or this of the race of that: to make good one, there is need of a great many others.
[Flesher ed. (1685)]

Folly is either of the house of lies, or lies are the house of folly, for in order to stand, each needs the support of many.
[tr. Fischer (1937)]

They say one lie leads to another, greater one, and it is the same with folly.
[tr. Maurer (1992)]
