“Let us not seek to satisfy our thirst for freedom by drinking from the cup of bitterness and hatred.”

XXV. Quoted in Hoyt's New Cyclopedia Of Practical Quotations (1922), p. 801-03.

Speech https://api.parliament.uk/historic-hansard/commons/1938/oct/05/policy-of-his-majestys-government#column_373 in the House of Commons (5 October 1938) against the Munich Agreement
The 1930s
Context: I do not grudge our loyal, brave people, who were ready to do their duty no matter what the cost, who never flinched under the strain of last week—I do not grudge them the natural, spontaneous outburst of joy and relief when they learned that the hard ordeal would no longer be required of them at the moment; but they should know the truth. They should know that there has been gross neglect and deficiency in our defences; they should know that we have sustained a defeat without a war, the consequences of which will travel far with us along our road; they should know that we have passed an awful milestone in our history, when the whole equilibrium of Europe has been deranged, and that the terrible words have for the time being been pronounced against the Western democracies: "Thou art weighed in the balance and found wanting." And do not suppose that this is the end. This is only the beginning of the reckoning. This is only the first sip, the first foretaste of a bitter cup which will be proffered to us year by year unless by a supreme recovery of moral health and martial vigour, we arise again and take our stand for freedom as in the olden time.

"Love"
The Forerunner (1920)
Context: O love, whose lordly hand
Has bridled my desires,
And raised my hunger and my thirst
To dignity and pride,
Let not the strong in me and the constant
Eat the bread or drink the wine
That tempt my weaker self.
Let me rather starve,
And let my heart parch with thirst,
And let me die and perish,
Ere I stretch my hand
To a cup you did not fill,
Or a bowl you did not bless.
