Cultural replication and microbial evolution

The aim of this paper is to argue that cultural evolution is in many ways much more similar to microbial than to macrobial biological evolution. As a result, we are better off using microbial evolution as the model of cultural evolution. And this shift from macrobial to microbial entails adjusting the theoretical models we can use for explaining cultural evolution

Perceiving tropes

There are two very different ways of thinking about perception. According to the first one, perception is representational: it represents the world as being a certain way. According to the second, perception is a genuine relation between the perceiver and a token object. These two views are thought to be incompatible. My aim is to work out the least problematic version of the representational view of perception that preserves the most important considerations in favor of the relational view. According to this version of representationalism, the properties represented in perception are tropes—abstract particulars that are logically incapable of being present in two distinct individuals at the same time. I call this view ‘trope representationalism

Blur and perceptual content

Intentionalism about visual experiences is the view according to which the phenomenal character of a visual experience supervenes on the content of this experience. One of the most influential objections to this view is about blur: seeing a fuzzy contour clearly and seeing a sharp contour blurrily have different phenomenal character but the same content. I argue that this objection does not work if we understand perceptual content simply, and not particularly controversially, as partly constituted by the sum total of perceptually attributed properties, some determinable, some determinate

Motor imagery and action execution

What triggers the execution of actions? What happens in that moment when an action is triggered? What mental state is there at the moment of action-execution that was not there a second before? My aim is to highlight the importance of a thus far largely ignored kind of mental state in the discussion of these old and much-debated questions: motor imagery. While there have been a fair amount of research in psychology and neuroscience on motor imagery in the last 30 years or so, it is only recently that we start to understand the important role motor imagery plays in action initiation. And if, as these findings suggest, motor imagery plays an important role in action initiation, we can make progress not only in understanding action initiation in general but also in understanding what goes wrong in akratic actions and in relapse actions. Finally, this new picture of action-initiation also has far-reaching consequences for the relation between motivation and causation in naturalistic action-explanations

The macro and the micro

Andreas Gursky is the darling of philosophers and art theorists of all kinds of traditions and denominations. He has been used as a prime example of the return of the sublime in contemporary art, as a trailblazer in the use of the digital manipulation of images in order to represent something abstract and even as a philosopher of perception who makes some subtle point about the nature of visual experience. All of these arguments are based on some or another technological innovation Gursky uses: the size of his photos, their postproduction (often digital) manipulation and their unusually high resolution. The aim of this paper is to shift the emphasis from these arguments on the significance of the new technology in Gursky’s oeuvre to a much more important role technology plays in his works, namely, in their aesthetics

Three ways of resisting essentialism about natural kinds

Essentialism about natural kinds has three tenets. The first tenet is that all and only members of a natural kind has some essential properties. The second tenet is that these essential properties play a causal role. The third tenet is that they are explanatorily relevant. I examine the prospects of questioning these tenets and point out that arguing against the first and the second tenets of kind-essentialism would involve taking parts in some of the grand debates of philosophy. But, at least if we restrict the scope of the discussion to the biological domain, the third tenet of kind-essentialism could be questioned more successfully

The role of imagination in decision-making

The psychological mechanism of decision-making has traditionally been modeled with the help of belief-desire psychology: the agent has some desires (or other pro-attitudes) and some background beliefs and deciding between two possible actions is a matter of comparing the probability of the satisfaction of these desires given the background beliefs in the case of the performance of each action. There is a wealth of recent empirical findings about how we actually make decisions that seems to be in conflict with this picture. My aim is to outline an alternative model that is consistent with these empirical findings. This alternative model emphasizes the role imagination plays in our decisions: when we decide between two possible actions, we imagine ourselves in the situation that we imagine to be the outcome of these two actions and then compare these two imaginings

Musical twofoldness

The concept of twofoldness plays an important role in understanding the aesthetic appreciation of pictures. My claim is that it also plays an important role in understanding the aesthetic appreciation of musical performances. I argue that when we are aesthetically appreciating the performance of a musical work, we are simultaneously attending to both the features of the performed musical work and the features of the token performance we are listening to. This twofold experience explains a number of salient aspects of our experience of musical performances, from the importance of instrumentality, to the multimodal character of this experience

Success semantics: the sequel

The aim of this paper is to reinterpret success semantics, a theory of mental content, according to which the content of a belief is fixed by the success conditions of some actions based on this belief. After arguing that in its present form, success semantics is vulnerable to decisive objections, I examine the possibilities of salvaging the core of this proposal. More specifically, I propose that the content of some very simple, but very important, mental states, the immediate mental antecedents of action, can be explained in this manne

Do we see apples as edible?

Do we (sometimes) perceive apples as edible? One could argue that it is just a manner of speaking to say so: we do not really see an object as edible, we see it as having certain shape, size and color and we only infer on the basis of these properties that it is. I argue that we do indeed see objects as edible, and do not just believe that they are. My argument proceeds in two steps. First, I point out that Susanna Siegel's influential argument in favor of the claim that we represent sortal properties perceptually does not work. Second, I argue that we can fix this argument if we replace the sortal property in question with the property of being edible, climbable or Q-able in genera
