Quoted in The Tyrants : 2500 Years of Absolute Power and Corruption (2006), p. 27 London: Quercus Publishing, ISBN 1905204965 , these derive from a statement by Suetonius, included below, in which he states these words were often used by Caligula, but imply that he was quoting the tragedian Accius.

The Saviors of God (1923)
Context: I strive to discover how to signal my companions before I die, how to give them a hand, how to spell out for them in time one complete word at least, to tell them what I think this procession is, and toward what we go. And how necessary it is for all of us together to put our steps and hearts in harmony.
To say in time a simple word to my companions, a password, like conspirators.
Yes, the purpose of Earth is not life, it is not man. Earth has existed without these, and it will live on without them. They are but the ephemeral sparks of its violent whirling.
Let us unite, let us hold each other tightly, let us merge our hearts, let us create — so long as the warmth of this earth endures, so long as no earthquakes, cataclysms, icebergs or comets come to destroy us — let us create for Earth a brain and a heart, let us give a human meaning to the superhuman struggle.
This anguish is our second duty.

The Unquiet Grave (1944)
Context: There is no hate without fear. Hate is crystallized fear, fear's dividend, fear objectivized. We hate what we fear and so where hate is, fear will be lurking. Thus we hate what threatens our person, our liberty, our privacy, our income, our popularity, our vanity and our dreams and plans for ourselves. If we can isolate this element in what we hate we may be able to cease from hating. Analyse in this way the hatred of ideas or of the kind of people whom we have once loved and whose faces are preserved in Spirits of Anger. Hate is the consequence of fear; we fear something before we hate; a child who fears noises becomes the man who hates them.
