Take any work on astronomy of the last century, or the beginning of ours. You will no longer find in it, it goes without saying, our tiny planet plac… - Peter Kropotkin

If we take all into consideration; if we realise the progress made in the gardening culture, and the tendency towards spreading its methods... if we watch the cultural experiments which are being made now—experiments today and realities tomorrow—and ponder over the resources kept in store by science, we are bound to say that it is utterly impossible to foresee at the present moment the limits as to the maximum number of human beings who could draw their means of subsistence from a given area of land, or as to what a variety of produce they could advantageously grow in any latitude.

The Roman Empire was a State in the real sense of the word. To this day it remains the legist's ideal. Its organs covered a vast domain with a tight network. Everything gravitated towards Rome: economic and military life, wealth, education, nay, even religion. From Rome came the laws, the magistrates, the legions to defend the territory, the prefects and the gods, The whole life of the Empire went back to the Senate — later to the Caesar, the all powerful, omniscient, god of the Empire. Every province, every district had its Capitol in miniature, its small portion of Roman sovereignty to govern every aspect of daily life. A single law, that imposed by Rome, dominated that Empire which did not represent a confederation of fellow citizens but was simply a herd of subjects. Even now, the legist and the authoritarian still admire the unity of that Empire, the unitarian spirit of its laws and, as they put it, the beauty and harmony of that organization. But the disintegration from within, hastened by the barbarian invasion; the extinction of local life, which could no longer resist the attacks from outside on the one hand nor the canker spreading from the centre on the other; the domination by the rich who had appropriated the land to themselves and the misery of those who cultivated it — all these causes reduced the Empire to a shambles, and on these ruins a new civilization developed which is now ours.

Few books have exercised so pernicious an influence upon the general development of economic thought as Malthus's Essay on the Principle of Population exercised for three consecutive generations. It appeared at the right time, like all books which have had any influence... and it summed up the ideas already current in the minds of the wealth-possessing minority. It was precisely when the ideas of equality and liberty, awakened by the French and American revolutions, were still permeating in the minds of the poor, while the richer classes had become tired of their amateur excursions into the same domains, that Malthus came to assert, in reply to Godwin, that no equality is possible; that the poverty of the many is not due to institutions, but is a natural law... and that law cannot be changed by any change of institutions.
