Mind-Dependence Idealism is the thesis that the world is mind-dependent. In particular, the things we call material objects are dependent on the mind for their existence: to be is to be perceived. Realism is the thesis that the world is mind-independent, so that material objects can exist whether perceived or not. Here is […]
Animal Deontology The moral theory usually applied to animal ethics is utilitarianism. We are to be concerned exclusively with the suffering and happiness of animals: we must minimize animal disutility and maximize animal utility. That, and only that, is what animals have a right to expect (transposing utilitarianism into a rights-based theory). […]
Perception and Emotion Everyone knows that sensory qualities are associated with emotions, though the manner of association is obscure. Colors suggest emotions (red passion, blue sadness); sounds are perceived emotionally especially in speech and music; tactile sensations are felt as pleasant or unpleasant; smells can be appetizing or revolting; tastes delicious […]
Mr. Spock and Captain Kirk Mr. Spock feels no emotion; Captain Kirk overflows with it. Spock coldly calculates; Kirk passionately emotes. Spock has no sense of humor and never smiles; Kirk enjoys a joke and smiles frequently. Kirk loves, not so Spock. Do they understand each other? It seems clear that […]
Are Reasons Causes? It used to be held in the 1950s that reasons are not causes (the “logical connection” argument), but the tide turned in the 1960s. The new orthodoxy was that rational explanation of actions is a species of causal explanation: beliefs and desires are the causes of action.[1] True, […]
Perception, Thought, and Language I will reflect loosely (though not I hope sloppily) on some very general properties of the items listed in the title, with special emphasis on their interrelations. There has been a tendency to assimilate these three things, as if they are all variations on a single theme. Empiricism […]
Heat, Color, Shape, and Taste Galileo’s 1623 discussion of heat and related matters bears revisiting.[1] In it he formulates with particular clarity what later came to be called the primary and secondary quality distinction, using it to address the question of whether motion is the cause of heat. He begins by saying […]
Existential Beliefs It is generally assumed in philosophy that we have a great many existential beliefs. We believe that objects in the external world exist, that other people exist, that we ourselves exist, that mental states exist, that space and time exist, etc. Maybe not everyone believes that atoms and numbers exist […]
Skepticism and Self-Knowledge From the point of view of skepticism, self-knowledge is an anomaly. How is it that facts about a person’s psychology can be known with certainty when everything else is uncertain? It’s not as if first-person ascriptions of mental states are analytic or a priori; they report the same […]
Roots of Skepticism The roots of skepticism run deep; they are not merely the invention of insecure philosophers. Perhaps the most primitive form of skepticism begins from a simple thought: belief is not the same as fact. Beliefs are in the mind; facts are in the world. Thus beliefs and […]
