Solidarity

According to Émile Durkheim, the types of social solidarity correlate with types of society. Durkheim introduced the terms mechanical and organic solidarity[9] as part of his theory of the development of societies in The Division of Labour in Society (1893). In a society exhibiting mechanical solidarity, its cohesion and integration comes from the homogeneity of individuals—people feel connected through similar work, educational and religious training, and lifestyle. Mechanical solidarity normally operates in traditional small-scale societies.[10] In tribal society, solidarity is usually based on kinship ties of familial networks. Organic solidarity comes from the interdependence that arises from specialization of work and the complementarities between people—a development which occurs in modern and industrial societies.[10]

Although individuals perform different tasks and often have different values and interests, the order and solidarity of society depends on their reliance on each other to perform their specified tasks. "Organic" refers to the interdependence of the component parts, and thus social solidarity is maintained in more complex societies through the interdependence of its component parts (e.g., farmers produce the food to feed the factory workers who produce the tractors that allow the farmer to produce the food).

Anarchist theorist Peter Kropotkin (1842–1921) connected the biological and the social in his formulation of solidarity. In his most famous book, Mutual Aid: A Factor of Evolution (1902), written partly in response to Huxleyan Social Darwinism, Kropotkin studied the use of cooperation as a survival mechanism in human societies at their various stages, as well as with animals. According to him, mutual aid, or cooperation, within a species has been an important factor in the evolution of social institutions. Solidarity is essential for mutual aid; supportive activity towards other people does not result from the expectation of reward, but rather from instinctive feelings of solidarity.

In his introduction to the book, Kropotkin wrote:

The number and importance of mutual-aid institutions which were developed by the creative genius of the savage and half-savage masses, during the earliest clan-period of mankind and still more during the next village-community period, and the immense influence which these early institutions have exercised upon the subsequent development of mankind, down to the present times, induced me to extend my researches to the later, historical periods as well; especially, to study that most interesting period—the free medieval city republics, whose universality and influence upon our modern civilization have not yet been duly appreciated. And finally, I have tried to indicate in brief the immense importance which the mutual-support instincts, inherited by mankind from its extremely long evolution, play even now in our modern society, which is supposed to rest upon the principle "every one for himself, and the State for all," but which it never has succeeded, nor will succeed in realizing".[11]

Kropotkin advocated an alternative economic and social system, which would be coordinated through a horizontal network of voluntary associations with goods distributed in compliance with the physical needs of the individual, rather than according to labour.[12]

Fritz Jahr describes bioethics as ultimately made up of "academic discipline, principle, and virtue".[15] This echoes back to the influence Socrates has on the norms of bioethics and its practices. Jahr utilizes Kant's Categorical Imperative to demonstrate the obligatory, yet innately human practice of the Bioethical Imperative:

[T]he guiding principle for our actions is the Bioethical Imperative: Respect every living being in general as an end in itself, and treat it if possible, as such[15]

as it arises in the relationships not only between people, but also with plants and other animal species. Jahr believes that in order to practice bioethics, one must be in solidarity with all forms of life.[15] If one only decides to be in solidarity in humans, then one should not behave virtuously in any manner.[16]
