“It is with logic as it is with other sciences. They draw wisdom from the mysterious source of plain experience. Agriculture, e. g., aims to teach the farmer how to cultivate the soil; but fields were tilled long before any agricultural college had begun its lectures. In the same way human beings think without ever having heard of logic. But by practice they improve their innate faculty of thought, they make progress, they gradually learn to make better use of it. Finally, just as the farmer arrives at the science of agriculture, so the thinker arrives at logic, acquires a clear consciousness of his faculty of thought and a professional dexterity in applying it.”

“If farmers become weak the country looses self-reliance but if they are strong, freedom also becomes strong. If we do not maintain our progress in agriculture, poverty cannot be eliminated from India.
But our biggest poverty alleviation programme is to improve the living standard of our farmers.
The thrust of our poverty alleviation programmes is on the uplift of the farmers.”

““Culture” means … the cultivation of the mind, the taking care and improving of the native faculties of the mind in accordance with the nature of the mind. Just as the soil needs cultivators of the soil, the mind needs teachers. But teachers are not as easy to come by as farmers. The teachers themselves are pupils and must be pupils. But there cannot be an infinite regress: ultimately there must be teachers who are not in turn pupils. Those teachers who are not in turn pupils are the great minds.”

“The subject of a science is never well circumscribed and there is little use sharpening its definition. However, nobody will deny that physics deals with nature and sociology with human society in some of their aspects. With logic, it is another matter. Logic is usually understood nowadays as a study of certain formal systems, though in former times there were philosophers who held that the subject matter of logic was the formal rules of human thought. In the latter sense it would be an empirical rather than a formal science, though its empirical subject matter would still be fundamentally different from that of psychology of thinking. One interpretation of logic does not exclude the other. Formal approaches are often easier than empirical ones, and for this reason one can understand why logic as a study of formal systems has till now made more progress than logic as a study of the formal rules of thought, even if restricted to scientific thought.”

“Logic is justly considered the basis of all other sciences, even if only for the reason that in every argument we employ concepts taken from the field of logic, and that ever correct inference proceeds in accordance with its laws.”

“The destruction of the old bonds between employers and workmen was not peculiar to manufactures; it came to pass in agriculture also. An agrarian as well as an industrial revolution had taken place. Scientific methods of cultivation had been substituted for unscientific; vast enclosures had been made; traces of the old three-field system of apportioning the land were fast disappearing; small farms were giving way to large. A new race of farmers, corresponding to the new race of manufacturers, had sprung into existence, who, enriched by the high prices which prevailed during the great war, changed their habits of life. The labourer ceased to be a member of the farmer's household, and, to use Cobbett's words, was thrust out of the farm-house into a hovel.”

“Thus, the Communists program for agriculture, universal for all countries, would expropriate entirely all farmers living above subsistence or its margin, who are eventually to be collectivized.”

“The only progress I can see is progress in organization. The ordinary human being does not live long enough to draw any substantial benefit from his own experience. And no one, it seems, can benefit by the experiences of others. Being both a father and teacher, I know we can teach our children nothing. We can transmit to them neither our knowledge of life nor of mathematics. Each must learn its lesson anew.”

““Life experience” does not amount to very much and could be learned from novels alone, e. g., from Balzac, without any help from life.”

“In speaking of agricultural management, the French say, I'economie rurale, and the English, rural economy; and yet neither the one nor the other intend thereby to signify the absolute execution of agricultural operations, but only the division and circumstances or appurtenances of agriculture. In Germany, where a Latin or Greek name has lately been thought to give dignity to a science, and has, consequently, been introduced into the title of most of the scientific works, some authors have begun to term, not only the science of agriculture, but agriculture itself, the oekonomie; and the word is used exclusively in this sense by many persons. It is for this reason that those who are supposed to practise the art with the greatest skill and science, are termed oekonomen (economists); and that some of those who are employed in superintending the labourers, even though they frequently have not the least idea of the actual principles of agriculture, chose to be designated by this title.”

“Logic is not concerned with human behavior in the same sense that physiology, psychology, and social sciences are concerned with it. These sciences formulate laws or universal statements which have as their subject matter human activities as processes in time. Logic, on the contrary, is concerned with relations between factual sentences (or thoughts). If logic ever discusses the truth of factual sentences it does so only conditionally, somewhat as follows: if such-and-such a sentence is true, then such-and-such another sentence is true. Logic itself does not decide whether the first sentence is true, but surrenders that question to one or the other of the empirical sciences.”
