Our different senses put us in contact with the same world. In this paper, I use unusual objects and situations to bring out structural dissimilarities in the way our senses relate to the same world of material objects. In the first part, I briefly discuss the perceptual presence of spatial and material things. Using uncommon objects allows me to treat this issue without any need to invoke what it is like to have visual experiences. What comes to the fore in these analyses, however, seems less obvious in experiences of the other senses. Therefore, in the second part, I propose a strategy, invoking unusual situations, to weed out the multisensory associations that enrich our normal relation to objects, in order to get a better grip on the perceptual correlate of the different senses. Although the actual correlates of the senses may not be material objects in each case, I explain why they are nonetheless occurrences in a spatial and material world.

From the outside, our senses are spatially integrated in our body in manifestly different ways. This paper starts from the suggestion that the philosophical formulation of the problem of spatial perception, as it flows from the modern opposition of mind and world, is partly responsible for the fact that philosophers have often explicitly disregarded the spatial nature of the senses themselves. An indirect consequence is that much philosophical work focuses on how the senses can – or cannot – perceive the same spatial features of objects in the same way, while disregarding the massive differences in performance among the senses. This paper explores the ways in which the spatial integration of our senses determines what each of our senses excels in, and hence what they contribute to our spatial relation to a physical environment. By juxtaposing descriptive analyses of a variety of selected cases, the paper gives priority to how various aspects of the world appear to us in order to obtain insight into the meaning of spatiality for different senses.

In recent philosophy of mind, a series of challenging ideas have appeared about the relation between the body and the sense of touch. In certain respects, these ideas have a striking affinity with Husserl’s theory of the constitution of the body. Nevertheless, these two approaches lead to very different understandings of the role of the body in perception. Either the body is characterized as a perceptual “organ,” or the body is said to function as a “template.” Despite its focus on the sense of touch, the latter conception, I will argue, nevertheless orients its understanding of tactual perception toward visual objects. This produces a distorted conception of touch. In this paper, I will formulate an alternative account, which is more faithful to what it is like to feel.

Because philosophical reflections on touch usually start from our ability to perceive properties of objects, they tend to overlook features of touch that are crucial to correct understanding of tactual perception. This paper brings out these features and uses them to develop a general reconception of the sense of touch. I start by taking a fresh look at our ability to feel, in order to reveal its vital role. This sheds a different light on the skin's perceptual potential. While it is commonly observed that tactile experiences have two intentional objects, an external object and one's own body, I will advance a more accurate alternative: in tactile experiences, one becomes aware of what one's body undergoes. This alternative not only fits better with tactility's vital role; it is also key to explaining how active touching provides for a unique contribution to our perceptual relation to material objects. By thus connecting tactility's vital role to the way we rely on touch while manipulating objects, this essay offers a cross-sectional survey of our tactile powers that reveals the interplay between sensing and touching.
