Creativity is generally thought to be the production of things that are novel and valuable. Humans are unique in the extent of their creativity, which plays a central role in innovation and problem solving, as well as in the arts. But what are the cognitive sources of novelty? More particularly, what are the cognitive sources of stochasticity in creative production? I will argue that they belong to two broad categories. One is associative, enabling the selection of goal-relevant ideas that have become activated by happenstance in an unrelated context. The other relies on selection processes that leverage stochastic fluctuations in neural activity. At the same time, I will address a central puzzle, which is to understand how the outputs of stochastic processes can nevertheless generally fall within task constraints. While the components appealed to in the accounts that I offer are well established, the ways in which I combine them together are new.

Humans have the capacity for awareness of many aspects of their own mental lives—their own experiences, feelings, judgments, desires, and decisions. We can often know what it is that we see, hear, feel, judge, want, or decide. This article examines the evolutionary origins of this form of self-knowledge. Two alternatives are contrasted and compared with the available evidence. One is first-person based: self-knowledge is an adaptation designed initially for metacognitive monitoring and control. The other is third-person based: self-knowledge depends on the prior evolution of a mindreading system which can then be directed toward the self. It is shown that the latter account is currently the best supported of the two

Many have argued that early visual processing is encapsulated from the influence of higher-level goals, expectations, and knowledge of the world. Here we confront the main arguments offered in support of such a view, showing that they are unpersuasive. We also present evidence of top–down influences on early vision, emphasizing data from cognitive neuroscience. Our conclusion is that encapsulation is not a defining feature of visual processing. But we take this conclusion to be quite modest in scope, readily incorporated into mainstream vision science.

This book develops in detail the simple idea that assertion is the expression of belief. In it the author puts forward a version of 'probabilistic semantics' which acknowledges that we are not perfectly rational, and which offers a significant advance in generality on theories of meaning couched in terms of truth conditions. It promises to challenge a number of entrenched and widespread views about the relations of language and mind. Part I presents a functionalist account of belief, worked through a modified form of decision theory. In Part II the author generates a theory of meaning in terms of 'assertibility conditions', whereby to know the meaning of an assertion is to know the belief it expresses.

This chapter considers whether any of the inner sense mechanisms that have been postulated to detect and represent some of our own mental states should qualify as sensory modalities. We first review and reject the four standard views of the senses, and then propose a set of properties that would be possessed by a prototypical sensory system. Thereafter we consider how closely the existing models of inner sense match the prototype. Some resemble a prototypical sense to a high degree, some much less so.

Our aim in this paper is to raise a question about the relationship between theories of responsibility, on the one hand, and a commitment to conscious attitudes, on the other. Our question has rarely been raised previously. Among those who believe in the reality of human freedom, compatibilists have traditionally devoted their energies to providing an account that can avoid any commitment to the falsity of determinism while successfully accommodating a range of intuitive examples. Libertarians, in contrast, have aimed to show that either physical indeterminacy or a certain kind of agent causation can find a place in the world for what they take to be genuine freedom. Few have considered whether moral responsibility requires a commitment to conscious attitudes.2 Our question derives from a confluence of two sources. First, there is reason to think that conscious attitudes matter to theories of responsibility, either directly, as a result of the latter’s commitments, or indirectly, by virtue of the assumptions that they make about certain intuitive examples. Second, there is accumulating evidence suggesting that there aren’t any conscious mental states possessing the sorts of causal roles required of propositional attitudes. Since theorists of responsibility should in general be concerned to make their views compatible with plausible claims about the natural world, the implications of this data should be carefully considered. Our aim is therefore to motivate and begin exploring answers to the following conditional question: If it should turn out that there are no conscious attitudes, then what would be the implications of this fact (if any) for theories of responsibility? We propose that theorists who aren’t skeptics about moral responsibility should examine their accounts, asking whether their theories (or the examples that motivate them) could survive the discovery that there are no conscious judgments, decisions, or evaluations. Since we take it that moral theorizing in general should operate with the weakest possible empirical assumptions about the natural world, such theorists should consider whether their accounts could be motivated in such a way as to be free of any commitment to the existence of conscious attitudes..

This chapter argues that our language faculty can both be a peripheral module of the mind and be crucially implicated in a variety of central cognitive functions, including conscious propositional thinking and reasoning. I also sketch arguments for the view that natural language representations (e.g. of Chomsky's Logical Form, or LF) might serve as a lingua franca for interactions (both conscious and non-conscious) between a number of quasi-modular central systems. The ideas presented are compared and contrasted with the evolutionary proposals made by Derek Bickerton (1990, 1995), who has also argued for the involvement of language in thought. Finally, I propose that it was the evolution of a mechanism responsible for pretend play, circa 40,000 years ago, which led to the explosion of creative culture visible in the fossil record from that time onwards
