Don’t express your ideas too clearly. Most people think little of what they understand, and venerate what they do not.

[No allanarse sobrado en el concepto. Los más no estiman lo que entienden, lo que no perciben lo veneran. Las cosas, para que se estiman, han de costar; será celebrado cuando no fuese entendido.]

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

The Art of Worldly Wisdom [Oráculo Manual y Arte de Prudencia], § 253 (1647) [tr. Maurer (1982)]

Alt. trans.: "Do not Explain overmuch. Most men do not esteem what they understand, and venerate what they do not see. ... Many praise a thing without being able to tell why, if asked. The reason is that they venerate the unknown as a mystery, and praise it because they hear it praised." [tr. Jacobs (1892)]
