Feeling the Brain You can feel your heart. It beats perceptibly in your chest. Before you ever knew what a heart was you could feel it in there. When you learned about its anatomy and physiology you had no trouble recognizing the thing you knew about before: you didn’t doubt […]
Father Time I liked it best when only I existed. That was a simpler time, a purer time. Good times. I stretched out to infinity in both directions with no beginning and no end. Nothing troubled me; nothing disturbed my peace. Moments, epochs, and eons—these were my units. Oh, I […]
Falsehood and Meaning In a famous paper entitled “Truth and Meaning” Donald Davidson argues that meaning is constituted by truth conditions. A recursive theory of truth for a language in the style of Tarski is thus a theory of meaning for that language. Understanding a sentence consists in grasping its […]
External Conditions of Thought The idea of the singular proposition is that propositions can contain particulars as well as universals as their constituents. If I think that that bird is pretty, my thought’s content contains both a particular bird and the general property of being pretty. Thus a singular thought […]
Explanations of Life Suppose we encounter life forms on another planet unrelated to ours and possibly quite unlike ours. Still, there is evident adaptive complexity, so that the laws of physics and chance cannot explain what we observe. What possible explanation might be given for this complexity? How might […]
Existence and the Cogito The Cogito strikes most people as intuitively valid, but it has been trenchantly criticized. How exactly the inference is supposed to work still excites controversy. Here I will consider a line of objection that I have not seen pressed before. The natural way to interpret the […]
Epistemology as Metaphysics We usually teach epistemology as a separate field from metaphysics. On the one hand, there is reality, the subject matter of metaphysics, and on the other there is knowledge of reality, the subject matter of epistemology. It is sometimes said that Descartes made epistemology the foundation […]
Distinctions and Differences There is distinction in the world and distinction in the mind: things differ and so do concepts. States of affairs differ and thoughts about them differ. But how are these distinctions related? Are they dependent or independent? Clearly there can be objective distinctions that are not mirrored […]
Dispositions and Perception Let’s start with something easy, before we get to more difficult questions. Namely: dispositions cannot be seen. You can gaze at salt for as long as you like and you will not be able to see its disposition to dissolve in water. It has that disposition, and it […]
Differentiation and Integration According to standard embryology, the process of ontogenesis is characterized by organic differentiation. From an initially homogeneous collection of cells tissues of various kinds are formed. This is no doubt powered by genetic instructions from within the original uniform cells. Maturation is thus a transformation from sameness to […]
