“As Cox points out, "Without inheritance, every class would be a free-standing unit, each developed from the ground up. Different classes would bear no relationship with one another, since the developer of each provides methods in whatever manner he Chooses. Any consistency across classes is the result of discipline on the part of the programmers. Inheritance makes it possible to define new software in the Same way we introduce any concept to a newcomer, by comparing it with something that is already familiar."”

“Object-oriented programming is a method of implementation in which programs are organized as cooperative collections of objects, each of which represents an instance of some class, and whose classes are all members of a hierarchy of classes united via inheritance relationships.”

“In place of the bourgeois society, with its classes and class antagonisms, shall we have an association, in which the free development of each is the condition for the free development of all.”

Karl Marx (1818–1883) German philosopher, economist, sociologist, journalist and revolutionary socialist

“I was not the one to invent lies: they were created in a society divided by class and each of us inherited lies when we were born. It is not by refusing to lie that we will abolish lies: it is by eradicating class by any means necessary.”

Jean Paul Sartre Dirty Hands

Act 5, sc. 3

“Legislative reform and revolution are not different methods of historic development that can be picked out at the pleasure from the counter of history, just as one chooses hot or cold sausages. Legislative reform and revolution are different factors in the development of class society. They condition and complement each other, and are at the same time reciprocally exclusive, as are the north and south poles, the bourgeoisie and proletariat.”

Rosa Luxemburg (1871–1919) Polish Marxist theorist, socialist philosopher, and revolutionary

“Forms of worship and spiritual discipline which may be valuable for one individual maybe useless or even positively harmful for another belonging to a different class and standing, within that class, at a lower or higher level of development.”

Aldous Huxley (1894–1963) English writer

Introduction to the Bhagavad-Gita (1944)
Context: Human beings are not born identical. There are many different temperaments and constitutions; and within each psycho-physical class one can find people at very different stages of spiritual development. Forms of worship and spiritual discipline which may be valuable for one individual maybe useless or even positively harmful for another belonging to a different class and standing, within that class, at a lower or higher level of development.

“An object which is used to create instances, i. e., a template, description, pattern, or "blueprint" of a category or collection of very similar items. Among other things, a class describes the interface the these items will present to the outside world, i. e., the available and appropriate methods, constants, and exceptions. A class represents an abstraction of the items. A class may itself be parameterized (i. e., it actually represents a family of very closely related classes), in which case we refer to it as a parameterized class. Class is a recursive concept. Specifically, we may define classes as being composed of other classes (i. e., heterogeneous composite classes and homogeneous composite classes), in terms of itself (a recursively defined class), as inheriting characteristics from one or more other classes (i. e., the superclasses of the class), and as providing characteristics to other classes (i. e., the subclasses of the class). In some places, classes are defined as "the set of all instances of a type," and the term "type" is given the above definition for class.”

“If chess has any relationship to film-making, it would be in the way it helps you develop patience and discipline in choosing between alternatives at a time when an impulsive decision seems very attractive.”

“Mathematics is in its development entirely free and is only bound in the self-evident respect that its concepts must both be consistent with each other, and also stand in exact relationships, ordered by definitions, to those concepts which have previously been introduced and are already at hand and established.”

Georg Cantor (1845–1918) mathematician, inventor of set theory

From Kant to Hilbert (1996)
Context: Mathematics is in its development entirely free and is only bound in the self-evident respect that its concepts must both be consistent with each other, and also stand in exact relationships, ordered by definitions, to those concepts which have previously been introduced and are already at hand and established. In particular, in the introduction of new numbers, it is only obligated to give definitions of them which will bestow such a determinacy and, in certain circumstances, such a relationship to the other numbers that they can in any given instance be precisely distinguished. As soon as a number satisfies all these conditions, it can and must be regarded in mathematics as existent and real.

“A development method may be regarded as a path or a procedure by which the developer proceeds from a problem of a certain class to a solution of a certain class. In trivial cases, the method may be fully algorithmic; for example, there is an algorithmic procedure for obtaining the square root of a nonnegative number to any desired degree of accuracy.”

Michael A. Jackson (1936) British computer scientist

“Education will enable young people quickly to familiarize themselves with the whole system of production and to pass from one branch of production to another in response to the needs of society or their own inclinations. It will, therefore, free them from the one-sided character which the present-day division of labor impresses upon every individual. Communist society will, in this way, make it possible for its members to put their comprehensively developed faculties to full use. But, when this happens, classes will necessarily disappear. It follows that society organized on a communist basis is incompatible with the existence of classes on the one hand, and that the very building of such a society provides the means of abolishing class differences on the other.”

Friedrich Engels (1820–1895) German social scientist, author, political theorist, and philosopher

(1847)
