 We turn now to the last dimension of socialism (DIII), which concerns the transformation of capitalist societies into socialist ones. The discussion on this dimension is difficult in at least two respects which call for philosophical exploration (Gilabert 2017a: 113–23, 2015: 216–20). The first issue concerns feasibility. The question is whether socialist systems are accessible from where we are now—whether there is a path from here to there. But what does feasibility mean here? It cannot just mean logical or physical possibility, as these would rule out very few social systems. The relevant feasibility parameters seem instead to involve matters of technical development, economic organization, political mobilization, and moral culture. (For some discussion on these parameters see Wright 2010: ch. 8; Chibber 2017.) But such parameters are comparatively “soft”, in that they indicate probability prospects rather than pose strict limits of possibility, and can be significantly changed over time. When something is not feasible to do right now, we could have dynamic duties to make it feasible to do later by developing our relevant capacities in the meantime. The feasibility judgments must then be scalar rather than binary and allow for diachronic variation. These features make them somewhat murky, and not straightforwardly amenable to the hard-edged use of impossibility claims to debunk normative requirements (via contraposition on the principle that ought implies can).
