Belief in secrets is an effective truth.

Si os la mostrara — replicó don Quijote — , ¿qué hiciérades vosotros en confesar una verdad tan notoria? La importancia está en que sin verla lo habéis de creer, confesar, afirmar, jurar y defender; donde no, conmigo sois en batalla, gente descomunal y soberbia.

It is always easier to believe than to deny. Our minds are naturally affirmative; it is not till the second or third thought that doubt begins. Belief is so vital and necessary that one would say the tendency was made strong at the perpetual risk of extra belief and superstition; it were better to believe too much than not enough. Hence mankind have always believed too much, as if to make sure that the anchor hold. To believe just enough, to free his mind from all cant and from all illusion, and see things just as in themselves they are, is the aim of the philosopher or of the true skeptic.

A secret's worth depends on the people from whom it must be kept.

Доверяй, но проверяй (Trust but Verify)

"Well, I shall tell you. My thesis is this, I want you to believe." "To believe what?" "To believe in things that you cannot."

piensas que algo difícil es imposible, nunca comenzarás a intentar conseguirlo. Creer en los secretos es una verdad efectiva.

You believe someone not because you have no doubts about them. Belief is not the absence of doubt. You believe someone because you don’t have enough doubts about them.

And do you think that unto such as you
A maggot-minded, starved, fanatic crew
God gave a secret, and denied it me?
Well, well — what matters it? Believe that, too!

The Secret is how to die. Since the beginning of time, the secret has always been how to die.

The secret is to fill your mind with thoughts of faith, confidence, and security.

To believe is to be happy; to doubt is to be wretched. To believe is to be strong. Doubt cramps energy. Belief is power. Only so far as a man believes strongly, mightily, can he act cheerfully, or do any thing that is worth the doing.

It is hard to prevent oneself from believing what one so keenly desires, and who can doubt that the interest we have in admitting or denying the reality of the Judgement to come determines the faith of most men in accordance with their hopes and fears.

I want you to believe...to believe in things that you cannot.
