“Objective pragmatism — or the pragmatism of the right, as Rescher calls it — implies that (a) our social-linguistic world evolved out of natural reality; (b) this social-linguistic world acquires an increasing autonomy; (c) between the social and the natural worlds there is no ontological line of separation, but just a functional one; (d) however, the accessibility to natural reality is only granted by the tools that the social-linguistic world provides us with; (e) this means that our knowledge of natural reality is always tentative and mediated by our conceptual capacities; (f) there is no need to draw relativistic conclusions from this situation, because the presence of an objective reality that underlies the data at hand puts upon personal desires objective constraints that we are able to overcome at the verbal level, but not in the sphere of rational deliberations implementing actions.”
