The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)

The empirical study of visual space has centered on determining its geometry, whether it is a perspective projection, flat or curved, Euclidean or non-Euclidean, whereas the topology of space consists of those properties that remain invariant under stretching but not tearing. For that reason distance is a property not preserved in topological space whereas the property of spatial order is preserved. Specifically the topological properties of dimensionality, orientability, continuity, and connectivity define “real” space as studied by physics and are the (...) spatial properties that characterize the physical universe as being an integral whole. By contrast the geometrical analysis of VS has taken little cognizance of its topology. Instead such properties have been presupposed a priori rather than being established a posteriori by empirical means, perhaps because these properties are self-evident. Applying the method of coordinative definition expounded by Hans Reichenbach for determining geometrical and topological properties of physical space, it can be shown that VS fulfills the topological criteria of being a “real” space sui generis. Though theorized to be produced by the brain, the topology of VS is not topologically equivalent with the structure and activity of the brain because, as will be shown, the topology of VS cannot be formed from the topology of the brain without tearing and/or cutting and pasting.

In current histories, C.I. Lewis is credited for bringing the strict concept of qualia – concerned solely with sensory states – into contemporary philosophy. It is this strict notion which is then credited with bringing in worries about inverted spectra, philosophical zombies, and the idea that we can individuate the senses introspectively. In this paper, I argue that this is a mistaken reading of Lewis and the history of qualia. I argue that the strict notion of qualia stems from the (...) work of Johannes Müller in the mid-nineteenth century and his work on individuating the senses. The structuralist psychologists who followed in his wake, in turn, developed an account where the qualitative character of experience played no causal role. I also show that Lewis adamantly rejects this strict concept of qualia. He instead endorses a pragmatic conception of qualia derived from William James in which evaluative states – such as the painfulness of pain – play an essential, causal role in the life of the organism. The upshot is that Lewis positions himself against the strict conception of qualia, arguing it is phenomenologically false and philosophically wrong-headed. (shrink)

Against the Newtonian view of color, according to which the world is colorless and colors are subjective sensations, phenomenologists keep insisting that colors are in the world. In order to defend this view of the “being in the world” of colors, this paper tries to elucidate the essential spatiality of colors on the basis of James’s thesis of the intrinsic spatiality of sensation, Katz’s phenomenological description of various spatial characters of color, and Gibson’s ecological optics. The noticeable correspondence between Katz’s (...) phenomenology and Gibson’s ecological optics indicates to us a possible way to an ecological phenomenology of colors. (shrink)
