This collection explores the structure of consciousness and its place in the world, or inversely the structure of the world and the place of consciousness in it. Amongst the topics covered are: the phenomenological aspects of experience, dependencies between experience and the world and the basic ontological categories found in the world at large. Developing ideas drawn from historical figures such as Descartes, Husserl, Aristotle, and Whitehead, the essays together demonstrate the interdependence of ontology and phenomenology and its significance for the philosophy of mind.

This is a study of the epistemology of indexical reference, Or its foundation in the intentionality of the speaker's awareness of the referent. Where the referent is the object of the speaker's acquaintance on that occasion, The sense expressed is the generic content of that awareness. This, Indexical sense determines indexical reference, But indexical sense works by appeal to the context of the speaker's awareness of the referent. It is discussed how, By virtue of indexical sense, Indexical reference is rigid, I.E. Picks out the same referent in any possible world

Phenomenology is the study of conscious experience from the first-person point of view. Husserl used principles of formal ontology even as he bracketed the natural-cultural world in describing our experience, and Heidegger pursued fundamental ontology in his variety of phenomenology describing our own modes of existence. I shall address the role of ontology in phenomenology, and vice versa. Our account of what exists depends on our account of what and how we experience. But, moreover, our understanding of the structure of consciousness depends on our understanding of structure, basic ontological structure, and hence of the place of consciousness in the structure of the world. What makes consciousness “hard” for contemporary philosophy of mind is understanding how intentionality and subjectivity fit into the structure of the world: how phenomenology fits with ontology.

Cognitive phenomenology may be defined as the study of “cognitive” experiences _as_ experienced, including consciously thinking, perceiving (sensory‐conceptual experience), judging (either self‐evidential or inferential), etc. The present study will address: (i) the _phenomenality_ of consciously thinking, i.e. its “appearing” in consciousness, with a character of “what it is like” to so think; (ii) the _intentionality_ of thinking, i.e. its character of being directed through a propositional content or “thought” toward a putative state of affairs; and (iii) the form of _inner awareness_ commonly found in thinking, i.e. the character whereby one is immediately aware of one's so thinking. On the “modal” model of consciousness, an act of _consciously_ thinking is _phenomenally_ directed _from_ the act, _centered_ in its subject, _through_ its meaning‐content _toward_ its putative object _with_ immediate awareness thereof. Several distinct “modal” characters will here be factored from the form of inner awareness: phenomenality, reflexivity, egocentricity, and temporal and spatial sensibility. On this account, phenomenality is not restricted to sensory experience bearing sensory “qualia.”

This chapter, which is concerned with the phenomenology of perception, especially the role of content and context in the intentionality of perception, tries to provide an account of the structure of perceptual experience and its intentional relation to its objects. In particular, it presents an analysis of consciousness and intentionality in perception. Perceptual experience is sensuous and paradigmatically intentional. The intentional character of a visual experience of an object is different to the successful intentional relation between the experience and the object. The twin-tomatoes experiment reveals that content alone does not settle which tomato is the correct object of perception. Perception gives a direct awareness of an object in the sense that the external object is itself the object of perception, and the object is actually present to the subject and experienced as actually present in the context of perception.

Over the past century phenomenology has ably analyzed the basic structuresof consciousness as we experience it. Yet recent philosophy of mind, lookingto brain activity and computational function, has found it difficult to makeroom for the structures of subjectivity and intentionality that phenomenologyhas appraised. In order to understand consciousness as something that is bothsubjective and grounded in neural activity, we need to delve into phenomenologyand ontology. I draw a fundamental distinction in ontology among the form,appearance, and substrate of any entity. Applying this three-facet ontology toconsciousness, we distinguish: the intentionality of consciousness ,the way we experience consciousness ,and the physical, biological, and cultural basis of consciousness .We can thus show how these very different aspects of consciousness fit togetherin a fundamental ontology. And we can thereby define the proper domains ofphenomenology and other disciplinesthat contribute to our understanding of consciousness

This essay explores an ideal notion of form (mathematical structure) that embraces logical, phenomenological, and ontological form. Husserl envisioned a correlation among forms of expression, thought, meaning, and object—positing ideal forms on all these levels. The most puzzling formal entities Husserl discussed were those he called ‘manifolds’. These manifolds, I propose, are forms of complex states of affairs or partial possible worlds representable by forms of theories (compare structuralism). Accordingly, I sketch an intentionality-based semantics correlating these four Husserlian levels of form—thereby integrating logic, phenomenology, and ontology.
