“The whole result of continued labour is not often consumed and enjoyed in a moment; the result generally lasts for a certain length of time. We must then conceive the capital as being progressively uninvested.”

"The Law and the Gospel" (1896)
Context: You cannot judge a man's life by the success of a moment, by the victory of an hour, or even by the results of a year. You must view his life as a whole. You must stand where you can see the man as he treads the entire path that leads from the cradle to the grave — now crossing the plain, now climbing the steeps, now passing through pleasant fields, now wending his way with difficulty between rugged rocks — tempted, tried, tested, triumphant.

1850s, Latter-Day Pamphlets (1850), Stump Orator (May 1, 1850)
Context: If a soul is born with divine intelligence, and has its lips touched with hallowed fire, in consecration for high enterprises under the sun, this young soul will find the question asked of him by England every hour and moment: "Canst thou turn thy human intelligence into the beaver sort, and make honest contrivance, and accumulation of capital by it? If so, do it; and avoid the vulpine kind, which I don't recommend. Honest triumphs in engineering and machinery await thee; scrip awaits thee, commercial successes, kingship in the counting-room, on the stock-exchange;—thou shalt be the envy of surrounding flunkies, and collect into a heap more gold than a dray-horse can draw. "—"Gold, so much gold?" answers the ingenuous soul, with visions of the envy of surrounding flunkies dawning on him; and in very many cases decides that he will contract himself into beaverism, and with such a horse-draught of gold, emblem of a never-imagined success in beaver heroism, strike the surrounding flunkies yellow. This is our common course; this is in some sort open to every creature, what we call the beaver career; perhaps more open in England, taking in America too, than it ever was in any country before. And, truly, good consequences follow out of it: who can be blind to them? Half of a most excellent and opulent result is realized to us in this way; baleful only when it sets up (as too often now) for being the whole result.

Anarchism: Its Philosophy and Ideal (1896)
Context: Harmony thus appears as a temporary adjustment, established among all forces acting upon a given spot — a provisory adaptation; and that adjustment will only last under one condition: that of being continually modified; of representing every moment the resultant of all conflicting actions. Let but one of those forces be hampered in its action for some time and harmony disappears. Force will accumulate its effect; it must come to light, it must exercise its action, and if other forces hinder its manifestation it will not be annihilated by that, but will end by upsetting the present adjustment, by destroying harmony, in order to find a new form of equilibrium and to work to form a new adaptation. Such is the eruption of a volcano, whose imprisoned force ends by breaking the petrified lavas which hindered them to pour forth the gases, the molten lavas, and the incandescent ashes. Such, also, are the revolutions of mankind.

Context: When you have the majority of a country up to the age of 55 already voting for independence, then I think the writing's on the wall for Westminster. I think Scots of my generation and above should be looking at themselves in the mirror and wonder if we by majority, as a result of our decision, have actually impeded progress for the next generation, something no generation should do. The destination is pretty certain – we're only now debating the timescale and the method. I'll contribute to that debate, but I think it's time for new leadership. There are a number of political opportunities coming up. For many, many years, a referendum route wasn't the chosen route of the SNP or Scotland. For many years, there was a gradual attitude to independence. You establish a parliament and establish successively more powers until you have a situation where you're independent in all but name, and then presumably declare yourself to be independent. Many countries have proceeded through that route – there is a parliamentary route where people can make their voice heard as well – so a referendum is only one of a number of routes. I think that’s the best route. That’s always been my opinion but my opinion is only one of many.

Si toutes les parties de l’univers sont solidaires dans une certaine mesure, un phénomène quelconque ne sera pas l’effet d’une cause unique, mais la résultante de causes infiniment nombreuses ; il est, dit-on souvent, la conséquence de l’état de l’univers un instant auparavant.

The Stark Munro Letters (1894)
Context: The more we progress the more we tend to progress. We advance not in arithmetical but in geometrical progression. We draw compound interest on the whole capital of knowledge and virtue which has been accumulated since the dawning of time. Some eighty thousand years are supposed to have existed between paleolithic and neolithic man. Yet in all that time he only learned to grind his flint stones instead of chipping them. But within our father's lives what changes have there not been? The railway and the telegraph, chloroform and applied electricity. Ten years now go further than a thousand then, not so much on account of our finer intellects as because the light we have shows us the way to more. Primeval man stumbled along with peering eyes, and slow, uncertain footsteps. Now we walk briskly towards our unknown goal.
