“Among the grievances of modern days, much complained of, but with little hope of redress, is the matter of receiving and paying visits, the number of which, it is generally agreed, “has been increasing, is increased, and ought to be diminished.”… Nor is this complaint by any means peculiar to the times in which we have the honour to live. Cowley was out of all patience on the subject above a hundred years ago. “If we engage,” says he, “in a large acquaintance, and various familiarities, we set open our gates to the invaders of most of our time; we expose our life to a ‘quotidian ague of frigid impertinencies,’ which would make a wise man tremble to think of.””

Kalki : or The Future of Civilization (1929)
Context: The East and the West are not so sharply divided as the alarmists would make us believe. The products of spirit and intelligence, the positive sciences, the engineering techniques, the governmental forms, the legal regulations, the administrative arrangements, and the economic institutions are binding together peoples of varied cultures and bringing them into closer reciprocal contact. The world today is tending to function as one organism.
The outer uniformity has not, however, resulted in an inner unity of mind and spirit. The new nearness into which we are drawn has not meant increasing happiness and diminishing friction, since we are not mentally and spiritually prepared for the meeting. Maxim Gorky relates how, after addressing a peasant audience on the subject of science and the marvels of technical inventions, he was criticized by a peasant spokesman in the following words : "Yes, we are taught to fly in the air like birds, and to swim in the water like the fishes, but how to live on the earth we do not know."
Among the races, religions, and nations which live side by side on the small globe, there is not that sense of fellowship necessary for good life. They rather feel themselves to be antagonistic forces. Though humanity has assumed a uniform outer body, it is still without a single animating spirit. The world is not of one mind. … The provincial cultures of the past and the present have not always been loyal to the true interests of the human race. They stood for racial, religious, and political monopolies, for the supremacy of men over women and of the rich over the poor. Before we can build a stable civilization worthy of humanity as a whole, it is necessary that each historical civilization should become conscious of its limitations and it's unworthiness to become the ideal civilization of the world.

It is also frequently said, when a quantity diminishes without limit, that it has nothing, zero or 0, for its limit: and that when it increases without limit it has infinity or ∞ or 1⁄0 for its limit.

Progress and Poverty (1879)
Context: It is true that wealth has been greatly increased, and that the average of comfort, leisure, and refinement has been raised; but these gains are not general. In them the lowest class do not share. I do not mean that the condition of the lowest class has nowhere nor in anything been improved; but that there is nowhere any improvement which can be credited to increased productive power. I mean that the tendency of what we call material progress is in nowise to improve the condition of the lowest class in the essentials of healthy, happy human life. Nay, more, that it is still further to depress the condition of the lowest class. The new forces, elevating in their nature though they be, do not act upon the social fabric from underneath, as was for a long time hoped and believed, but strike it at a point intermediate between top and bottom. It is as though an immense wedge were being forced, not underneath society, but through society. Those who are above the point of separation are elevated, but those who are below are crushed down.
