A supramodal thorough account of the Molyneux question

In this paper, we want to tackle the Molyneux question thoroughly, by addressing it in terms of both ordinary perception and pictorial perception: if a congenitally blind person recovered sight, could she recognize visually the 3D shapes she already recognized tactilely, both when such shapes are given to her directly and when they are given to her pictorially, i.e., as depicted shapes? We want to claim that empirical evidence suggests that the question can be positively answered in both cases. For in the first case, such evidence shows that perception of 3D shapes is supramodal; namely, it can be equivalently achieved in different sense modalities, notably touch and vision, independently of the sensory input such shapes are accessed. While in the second case, such evidence shows that one can satisfy both in vision and in touch the condition for depicted shapes, which are typically not where the perceiver is, to be grasped by that perceiver in a picture’s subject, i.e., what the picture presents. This condition states that the picture’s vehicle, i.e., the typically 2D physical basis of a picture, is enriched by adding to its properties the 3D grouping properties that allow for a figure/ground segmentation to be performed in that vehicle’s elements.
