Aristotle, selection from Rhetoric (Book I, Part 2)

Written about 350 B.C., these three terms—logos, ethos, and pathos—still form the basis of rhetoric as it is taught considerably more than two thousand years later.

Of the modes of persuasion furnished by the spoken word there are three kinds. The first kind depends on the personal character of the speaker; the second on putting the audience into a certain frame of mind; the third on the proof, or apparent proof, provided by the words of the speech itself. Persuasion is achieved by the speaker’s personal character when the speech is so spoken as to make us think him credible. We believe good men more fully and more readily than others: this is true generally whatever the question is, and absolutely true where exact certainty is impossible and opinions are divided. This kind of persuasion, like the others, should be achieved by what the speaker says, not by what people think of his character before he begins to speak. It is not true, as some writers assume in their treatises on rhetoric, that the personal goodness revealed by the speaker contributes nothing to his power of persuasion; on the contrary, his character may almost be called the most effective means of persuasion he possesses. Secondly, persuasion may come through the hearers, when the speech stirs their emotions. Our judgments when we are pleased and friendly are not the same as when we are pained and hostile. It is towards producing these effects, as we maintain, that present-day writers on rhetoric direct the whole of their efforts. This subject shall be treated in detail when we come to speak of the emotions. Thirdly, persuasion is effected through the speech itself when we have proved a truth or an apparent truth by means of the persuasive arguments suitable to the case in question.

There are, then, these three means of effecting persuasion. The man who is to be in command of them must, it is clear, be able (1) to reason logically, (2) to understand human character and goodness in their various forms, and (3) to understand the emotions—that is, to name them and describe them, to know their causes and the way in which they are excited.

Winston Churchill, selections from his speech to the House of Commons on 18 June 1940

On 10 May 1940, Germany began a massive attack against Holland, Belgium, Luxembourg, and France. Defending those countries were the British Expeditionary Force along with the French, Belgian, and Dutch armies.

After just a few weeks, Hitler’s armies won victories on all fronts. Holland, Luxembourg, and Belgium surrendered by the end of May. Paris fell on 14 June. Three days later, France sued for peace.

With the realization that Britain now stands alone against Germany, British Prime Minister gave the following speech in the House of Commons on 18 June 1940.

The disastrous military events which have happened during the past fortnight have not come to me with any sense of surprise. Indeed, I indicated a fortnight ago as clearly as I could to the House that the worst possibilities were open; and I made it perfectly clear then that whatever happened in France would make no difference to the resolve of Britain and the British Empire to fight on, if necessary for years, if necessary alone…

We do not yet know what will happen in France or whether the French resistance will be prolonged, both in France and in the French Empire overseas. The French Government will be throwing away great opportunities and casting adrift their future if they do not continue the war in accordance with their treaty obligations, from which we have not felt able to release them. The House will have read the historic declaration in which, at the desire of many Frenchmen—and of our own hearts—we have proclaimed our willingness at the darkest hour in French history to conclude a union of common citizenship in this struggle. However matters may go in France or with the French Government, or other French Governments, we in this Island and in the British Empire will never lose our sense of comradeship with the French people. If we are now called upon to endure what they have been suffering, we shall emulate their courage, and if final victory rewards our toils they shall share the gains, aye, and freedom shall be restored to all. We abate nothing of our just demands; not one jot or tittle do we recede. Czechs, Poles, Norwegians, Dutch, Belgians have joined their causes to our own. All these shall be restored.

What General Weygand called the is over. I expect that the is about to begin. Upon this battle depends the survival of Christian civilization. Upon it depends our own British life, and the long continuity of our institutions and our Empire. The whole fury and might of the enemy must very soon be turned on us.

Hitler knows that he will have to break us in this Island or lose the war. If we can stand up to him, all Europe may be free and the life of the world may move forward into broad, sunlit uplands. But if we fail, then the whole world, including the United States, including all that we have known and cared for, will sink into the abyss of a new Dark Age made more sinister, and perhaps more protracted, by the lights of perverted science.

Let us therefore brace ourselves to our duties, and so bear ourselves that if the British Empire and its Commonwealth last for a thousand years, men will still say, “This was their finest hour.”
