In the Logical Investigations, Ideas I and many other texts, Husserl maintains that perceptual consciousness involves the intentional “animation” or interpretation of sensory data or hyle, e.g., “color-data,” “tone-data,” and algedonic data. These data are not intrinsically representational nor are they normally themselves objects of representation, though we can attend to them in reflection. These data are “immanent” in consciousness; they survive the phenomenological reduction. They partly ground the intuitive or “in-the-flesh” aspect of perception, and they have a determinacy of character that we do not create but can only discover. This determinate, non-representational stratum of perceptual consciousness also serves as a bridge between consciousness and the world beyond it. I articulate and defend this conception of perceptual consciousness. I locate the view in the space of contemporary positions on phenomenal character and argue for its superiority. I close by briefly arguing that the Husserlian account is perfectly compatible with physicalism (this involves disarming the Grain Problem)

Hume's examination of the causal maxim in 1.3.3 of A Treatise of Human Nature can be considered, at least in part, a thinly veiled critique of the cosmological argument, attacking as it does the privileged status of the principle upon which that proof rests. As well, Hume's remarks on the impossibility of demonstrating matters of fact a priori in Part 3 of Section 12 of An Enquiry concerning Human Understanding clearly strike at the heart of the ontological argument, even if not explicitly. Unfortunately, it is only in the very brief Part 9 of his Dialogues Concerning Natural Religion that Hume directly discusses, at any length, the attempt to demonstrate a priori the existence of a deity. The argument, put forward by Demea, and Cleanthes's criticism of that argument take up so little space that for ease of reference I will reproduce them before we proceed any further. Part 9 consists of eleven paragraphs, and in accordance with a now fairly common convention, I will refer to the paragraphs by number. I reproduce only those paragraphs that will be the focus of this paper.

I aim to provide some evidence that Husserl’s description of perceptual updating actually fits very nicely into the Bayesian Brain paradigm, articulated by Karl Friston and others, and that that paradigm, in turn, can be taken as an excellent example of “Neurophenomenology”. The apparently un-phenomenological Helmholtzian component of the Bayesian Brain paradigm, according to which what one consciously seems to see is a product of unconscious causal reasoning to the best explanation of one’s sensory stimulations, can be finessed, I claim, in a way that makes it compatible with a phenomenological orientation. I begin by roughly characterizing the Bayesian Brain paradigm as it relates to perceptual cognition. I then show how Husserl’s descriptions of the conscious perceptual process relate to the paradigm. I conclude with some considerations about how to understand the relation between conscious and unconscious brain process in the present case and in relation to Neurophenomenology generally.
