When we look forward and try to project what may come out of a development, we are always wrong, because the by-products sometimes become far more important than the primary thing you started out to accomplish. Nevertheless, unintelligent motion is a great deal more important in research than intelligent standing still.

There ain’t nobody on earth, I don’t care how smart they are, ever going to make me believe they will ever stop wars.
An economist is a man that can tell you anything about — he’ll tell you what can happen under any given conditions, and his guess is liable to be just as good as anybody else’s, too.
People often overestimate what will happen in the next two years and underestimate what will happen in ten.

Perhaps if we saw what was ahead of us, and glimpsed the crimes, follies, and misfortunes that would befall us later on, we would all stay in our mother’s wombs, and there would be nobody in the world but a great number of very fat, very irritated women.

The End (2006)
I do so wish sometimes, that I could just pop home for an hour or two as easily in the flesh as in the spirit. No doubt the explorers of 2015, if there is anything left to explore, will not only carry their pocket wireless telephones fitted with wireless telescopes but will also receive their nourishment and warmth by wireless means & also their power to drive their motor sledges, but, of course, there will be an aerial daily excursion to both Poles then & it will be the bottom of the Atlantic, if not the centre of the earth, that will form the goal in those days.
Thomas Orde-Lees (1877-1948) British naval officer, arctic explorer, mountaineer, writer
Diary, aboard HMS Endurance (1915-01-10)
Written while the ship was trapped in the ice during Ernest Shackleton's ill-fated Imperial Trans-Antarctic Expedition. Some versions of the quotation refer to "2012," rather than 2015.
While the reference to "pocket wireless telephones" makes this quotation suspect, Orde-Lees has extensive diary material published, and this appears to be genuine.
After titanic studies he was satisfied that a thorough knowledge of the past could lead a profound scholar to predict the future course of history with greater accuracy, provided that it did not turn out quite differently.

Men of all degrees should form this prudent habit:
Never serve a rabbit stew before you catch the rabbit.James Thurber (1894-1961) American cartoonist and writer
“Ivory, Apes, and People,” Further Fables for Our Time (1956)
Prudent men are in the habit of saying — and not by chance or without basis — that he who wishes to see what is to come should observe what has already happened, because all the affairs of the world, in every age, have their individual counterparts in ancient times. The reason for this is that since they are carried on by men, who have and always have had the same passions, of necessity the same results appear.
Niccolò Machiavelli (1469-1527) Italian politician, philosopher, political scientist
The Discourses on Livy, Book 3, ch. 43 (1517) [tr. Gilbert (1958)]

Alt. trans.: "The wise are wont to say, and not without reason or at random, that he who would forecast what is about to happen should look to what has been; since all human events, whether present or to come, have their exact counterpart in the past. And this, because these events are brought about by men, whose passions and dispositions remaining in all ages the same naturally give rise to the same effects." [tr. Thomson]
The future always arrives too fast — and in the wrong order.

How many things have been denied one day, only to become realities the next!

Yes, but water decomposed into its primitive elements … and decomposed doubtless, by electricity, which will then have become a powerful and manageable force, for all great discoveries, by some inexplicable law, appear to agree and become complete at the same time. Yes, my friends, I believe that water will one day be employed as fuel, that hydrogen and oxygen which constitute it, used singly or together, will furnish an inexhaustible source of heat and light, of an intensity of which coal is not capable. Some day the coalrooms of steamers and the tenders of locomotives will, instead of coal, be stored with these two condensed gases, which will burn in the furnaces with enormous calorific power. There is, therefore, nothing to fear. As long as the earth is inhabited it will supply the wants of its inhabitants, and there will be no want of either light or heat as long as the productions of the vegetable, mineral or animal kingdoms do not fail us. I believe, then, that when the deposits of coal are exhausted we shall heat and warm ourselves with water. Water will be the coal of the future!

You have no lease of your lives, and death is not bound to give you warning before it gives you that deadly blow that will send you to everlasting misery or everlasting felicity.
Thomas Brooks (1608-1680) English Puritan divine, writer
The Hypocrite Detected, Anatomized (1650)
Science is as yet in its infancy, and we can foretell little of the future save that the thing that has not been is the thing that shall be; that no beliefs, no values, no institutions are safe. So far from being an isolated phenomenon the late war is only an example of the disruptive result that we may constantly expect from the progress of science. The future will be no primrose path. It will have its own problems. Some will be the secular problems of the past, giant flowers of evil blossoming at last to their own destruction. Others will be wholly new. Whether in the end man will survive his ascensions of power we cannot tell. But the problem is no new one. It is the old paradox of freedom re-enacted with mankind for actor and the earth for stage.

Forecast: To observe that which has passed, and guess it will happen again; to anticipate the future by guessing at the past; to predict that an event will happen, if it does, by basing calculations on events that have already happened, if they did.

Deserves death! I daresay he does. Many that live deserve death. And some die that deserve life. Can you give that to them? Then be not too eager to deal out death in the name of justice, fearing for your own safety. Even the wise cannot see all ends.

Frodo recalling the words of Gandalf (approximately) in The Fellowship of the Ring.
The tactical result of an engagement forms the base for new strategic decisions because victory or defeat in a battle changes the situation to such a degree that no human acumen is able to see beyond the first battle. In this sense one should understand Napoleon’s saying: “I have never had a plan of operations.” Therefore no plan of operations extends with any certainty beyond the first contact with the main hostile force.
Helmuth von Moltke (1800-1891) Prussian soldier
“On Strategy” (1871)
Translated in Daniel J. Hughes, Harry Bell, Moltke on the Art of War: Selected Writings (1993).
Paraphrases / variants:
- "No plan survives contact with the enemy."
- "No battle plan ever survives contact with the enemy."

But this long run is a misleading guide to current affairs. In the long run we are all dead. Economists set themselves too easy, too useless a task, if in tempestuous seasons they can only tell us, that when the storm is long past, the ocean is flat again.
An economist is an expert who will know tomorrow why the things he predicted yesterday didn’t happen today.
