“Science frees us in many ways…from the bodily terror which the savage feels. But she replaces that, in the minds of many, by a moral terror which is far more overwhelming.”

And Death glares grim in many a form.”

The Saviors of God (1923)
Context: The moment is ripe: leave the heart and the mind behind you, go forward, take the third step.
Free yourself from the simple complacency of the mind that thinks to put all things in order and hopes to subdue phenomena. Free yourself from the terror of the heart that seeks and hopes to find the essence of things.
Conquer the last, the greatest temptation of all: Hope. This is the third duty.

Variant translations:
The attribute of popular government in a revolution is at one and the same time virtue and terror. Terror without virtue is fatal; virtue without terror is impotent. The terror is nothing but justice, prompt, severe, inflexible; it is thus an emanation of virtue.
As quoted in Red Star Over Southern Africa (1988) by Morgan Norval, p. xvi
If the mainspring of popular government in peace time is virtue, its resource during a revolution is at one and the same time virtue and terror; virtue, without which terror is merely terrible; terror, without which virtue is simply powerless.
As quoted in Rousseau, Robespierre and English Romanticism (1999) by Gregory Dart
Terror is nothing other than justice, prompt, severe, inflexible; it is therefore an emanation of virtue; it is not so much a special principle as it is a consequence of the general principle of democracy applied to our country's most urgent needs.
Original French: La terreur n'est autre chose que la justice prompte, sévère, inflexible; elle est donc une émanation de la vertu ; elle est moins un principe particulier, qu’une conséquence du principe général de la démocratie, appliqué aux plus pressants besoins de la patrie.

1961, Inaugural Address
Context: So let us begin anew — remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear. But let us never fear to negotiate.
Let both sides explore what problems unite us instead of belaboring those problems which divide us. [... ] Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
Let both sides unite to heed in all corners of the earth the command of Isaiah — to "undo the heavy burdens … and to let the oppressed go free."
