The best maxim I know in life, is to drink your coffee when you can, and when you cannot, to be easy without it; while you continue to be splenetic, count upon it I will always preach. Thus much I sympathize with you, that I am not cheerful enough to write, for, I believe, coffee once a week is necessary, and you know very well that coffee makes us severe, and grave, and philosophical.

These various references to coffee are thought to have been based upon an incident in the early days of their friendship, when on the occasion of the Vanhomrigh family journeying from Dublin to London, Vanessa accidentally spilt her coffee in the chimney-place at a certain inn, which Swift considered a premonition of their growing friendship. Writing from Clogher, Swift reminds Vanessa:

Remember that riches are nine parts in ten of all that is good in life, and health is the tenth—drinking coffee comes long after, and yet it is the eleventh, but without the two former you cannot drink it right.

In another letter he writes facetiously, in memory of her playful badinage:

I long to drink a dish of coffee in the sluttery and hear you dun me for a secret, and "Drink your coffee; why don't you drink your coffee?"

Leigh Hunt had very pleasant things to say about coffee, giving to it the charm of appeal to the imagination, which he said one never finds in tea. For example:

Coffee, like tea, used to form a refreshment by itself, some hours after dinner; it is now taken as a digester, right upon that meal or the wine, and sometimes does not even close it; or the digester itself is digested by a liquor of some sort called a Chasse-Café [coffee-chaser]. We like coffee better than tea for taste, but tea "for a constancy." To be perfect in point of relish (we do not say of wholesomeness) coffee should be strong and hot, with little milk and sugar. It has been drunk after this mode in some parts of Europe, but the public have nowhere, we believe, adopted it. The favorite way of taking it at a meal, abroad, is with a great superfluity of milk—very properly called, in France café au lait (coffee to the milk). One of the pleasures we receive in drinking coffee is that, being the universal drink in the East, it reminds of that region of the "Arabian Nights" as smoking does for the same reason; though neither of these refreshments, which are identified with Oriental manners, is to be found in that enchanting work. They had not been discovered when it was written; the drink then was sherbet. One can hardly fancy what a Turk or a Persian could have done without coffee and a pipe, any more than the English ladies and gentlemen, before the civil wars, without tea for breakfast.

In his old age, Immanuel Kant, the great metaphysician, became extremely fond of coffee; and Thomas de Quincey relates a little incident showing Kant's great eagerness for the after-dinner cup.

At the beginning of the last year of his life, he fell into a custom of taking, immediately after dinner, a cup of coffee, especially on those days when it happened that I was of his party. And such was the importance that he attached to his little pleasure that he would even make a memorandum beforehand, in the blank paper book that I had given him, that on the next day I was to dine with him, and consequently "that there was to be coffee." Sometimes in the interest of conversation, the coffee was forgotten, but not for long. He would remember and with the querulousness of old age and infirm health would demand that coffee be brought "upon the spot." Arrangements had always been made in advance, however; the coffee was ground, and the water was boiling: and in the very moment the word was given, the servant shot in like an arrow and plunged the coffee into the water. All that remained, therefore, was to give it time to boil up. But this trifling delay seemed unendurable to Kant. If it were said, "Dear Professor, the coffee will be brought up in a moment," he would say, "Will be! There's the rub, that it only will be." Then he would quiet himself with a stoical air, and say, "Well, one can die after all; it is but dying; and in the next world, thank God, there is no drinking of coffee and consequently no waiting for it."

When at length the servant's steps were heard upon the stairs, he would turn round to us, and joyfully call out: "Land, land! my dear friends, I see land."
