Abstract
This article presents what I call the Central Normative Proposal of Luis Villoro. This proposal is based on an interpretation of the principle of non-exclusion in ethics and epistemology. The core argument of the paper
is based on a linguistic analogy that demonstrates the importance of reasonable communication for non-exclusion in epistemology, which is assumed in various theses of Villoro. A consequence of this analogy for non-exclusion in ethics is that Villoro defends basing what is reasonable on the concrete possibilities of mutual understanding, starting with asymmetries and injustices that are obfuscated or eliminated in a contractualist analysis, or one
that begins with strictly egalitarian principles. This criticism is compatible with egalitarian views, but it assumes a radically different point of departure. Although various theses by Villoro are compatible with egalitarian notions,
given this point of departure based on asymmetries of power his proposal should be understood based on our cognitive capacities to understand and appreciate such asymmetries. For this reason, the paper concludes with an analysis of the notion of reasonableness, which under my interpretation Villoro defines in terms of our capacities for attention, that are not reducible to beliefs or systems of beliefs. In this way, the Central Normative Proposal
of Villoro depends on the convergence between truth and the dignity of the members of communities in which as matter-of-fact asymmetries exist and must be eliminated through concrete communicative efforts.
