 Socialists have deployed ideals and principles of equality, democracy, individual freedom, self-realization, and community or solidarity. Regarding equality, they have proposed strong versions of the principle of equality of opportunity according to which everyone should have “broadly equal access to the necessary material and social means to live flourishing lives” (Wright 2010: 12; Roemer 1994a: 11–4; Nielsen 1985). Some, but by no means all, socialists construe equality of opportunity in a luck-egalitarian way, as requiring the neutralization of inequalities of access to advantage that result from people’s circumstances rather than their choices (G.A. Cohen 2009: 17–9). Socialists also embrace the ideal of democracy, requiring that people have “broadly equal access to the necessary means to participate meaningfully in decisions” affecting their lives (Wright 2010: 12; Arnold n.d.  [OIR]:  sect. 4). Many socialists say that democratic participation should be available not only at the level of governmental institutions, but also in various economic arenas (such as within the firm). Third, socialists are committed to the importance of individual freedom. This commitment includes versions of the standard ideas of negative liberty and non-domination (requiring security from inappropriate interference by others). But it also typically includes a more demanding, positive form of self-determination, as the “real freedom” of being able to develop one’s own projects and bring them to fruition (Elster 1985: 205; Gould 1988: ch. 1; Van Parijs 1995: ch. 1; Castoriadis 1979). An ideal of self-realization through autonomously chosen activities featuring people’s development and exercise of their creative and productive capacities in cooperation with others sometimes informs socialists’ positive views of freedom and equality—as in the view that there should be a requirement of access to the conditions of self-realization at work (Elster 1986: ch. 3). Finally, and relatedly, socialists often affirm an idea of community or solidarity, according to which people should organize their economic life so that they treat the freedom and well-being of others as intrinsically significant. People should recognize positive duties to support other people, or, as Einstein (1949) put it, a “sense of responsibility for [their] fellow men”. Or, as Cohen put it, people should “care about, and, where necessary and possible, care for, one another, and, too, care that they care about one another” (G.A. Cohen 2009: 34–5). Community is sometimes presented as a moral ideal which is not itself a demand of justice but can be used to temper problematic results permitted by some demands of justice (such as the inequalities of outcome permitted by a luck-egalitarian principle of equality of opportunity (G.A. Cohen 2009)). However, community is sometimes presented within socialist views as a demand of justice itself (Gilabert 2012). Some socialists also take solidarity as partly shaping a desirable form of “social freedom” in which people are able not only to advance their own good but also to act with and for others (Honneth 2015 [2017: ch. I]).
