“¡Atrévete a ser prudente! Energía y espíritu son necesarios para superar los obstáculos que tanto la indolencia de la naturaleza como la cobardía del corazón oponen a nuestra instrucción.”

Original

Dare to be wise! Energy and spirit is needed to overcome the obstacles which indolence of nature as well as cowardice of heart oppose to our instruction.

Letter 8; Variant: The greater part of men are much too exhausted and enervated by their struggle with want to be able to engage in a new and severe contest with error. Satisfied if they themselves can escape from the hard labour of thought, they willingly abandon to others the guardianship of their thoughts.

It is not without significance that the old myth makes the goddess of Wisdom emerge fully armed from the head of Jupiter; for her very first function is warlike. Even in her birth she has to maintain a hard struggle with the senses, which do not want to be dragged from their sweet repose. The greater part of humanity is too much harassed and fatigued by the struggle with want, to rally itself for a new and sterner struggle with error. Content if they themselves escape the hard labor of thought, men gladly resign to others the guardianship of their ideas, and if it happens that higher needs are stirred in them, they embrace with a eager faith the formulas which State and priesthood hold in readiness for such an occasion.
