The text seeks for a brief census of some of the main forms of a sceptical discourse on the problem of the the attribution of aesthetical qualities to objects: the major aim of this set must be undestood as an attack on the perceptive origin of sensible facts. The author comes back to resources, such as the dialogue between phenomenological and analytic philosophy traditions (especially in G.Ryle's works) so as to the L.Wittgenstein's interrogations on the status of aesthetical investigations: in those ambiences, they identify the necessity of converting the issue of the images as perceptual facts to a gramatical description of the judgements involving such experiences. The text indicates, finally, in the scope of the anti-cartesian texts by Ch.S.Peirce the main resources of an aesthetical theory coming from a philosophy of discursivity, applied to the perceptive judgements: his theory of semiotics constitutes, indeed, a radical transformation of some problems on inference, in the direction of a theory of the ampliative, or synthetic, forms of the understanding (mainly, the justification for the validity of hypothetical and inductive procedures, in science and in the description of denotative judgements).
