“It is a course which perhaps would not have been necessary had it been possible to form a state composed of wise men, but as every multitude is fickle, full of lawless desires, unreasoned passion, and violent anger, the multitude must be held in by invisible terrors and suchlike pageantry. For this reason I think, not that the ancients acted rashly and at haphazard in introducing among the people notions concerning the gods and beliefs in the terrors of hell, but that the moderns are most rash and foolish in banishing such beliefs.”
Histories, VI, 56:10-12
Often quoted in the version found in The Fine Art of Baloney Detection by Carl Sagan from The Demon-Haunted World:
Since the masses of the people are inconstant, full of unruly desires, passionate, and reckless of consequences, they must be filled with fears to keep them in order. The ancients did well, therefore, to invent gods, and the belief in punishment after death.

Book of Taliesin (c. 1275?), The Battle of the Trees
Context: I have been in a multitude of shapes,
Before I assumed a consistent form.
I have been a sword, narrow, variegated,
I will believe when it is apparent.
I have been a tear in the air,
I have been the dullest of stars.
I have been a word among letters,
I have been a book in the origin.
I have been the light of lanterns,
A year and a half.
I have been a continuing bridge,
Over three score river mouths.

Context: We understand the anger, the anguish and suffering which this act of international terrorism has created amongst people.
What we are worried about is the impact of the wrong kind of response to it. … We believe that the civilised world is a multicultural, multi-religious world. That is the type of message we want to get across. … I think there are many who are Muslims and non-Muslims, who are not warmongers but peace makers and want this world to be a better place.
We believed the unison of the voices of so many people standing together against international terrorism is something to be valued and something to be built upon.
