Description: This thesis examines the widespread intuition that the use of dynamical systems theory in cognitive science is related to the doctrine of emergentism about the mind. I start by distinguishing two varieties of this intuition, labeling them "strong" and "weak." I then set out the empirical and theoretical details of five canonical models in dynamical cognitive science, which have proven to be particularly philosophically salient.I then examine the concept of emergence from an interdisciplinary perspective, noting the variety of ways it has been used in cognitive science. I distinguish four different senses of the term "emergence" which I call "non-technical," "weak epistemological," "strong epistemological" and "ontological." I argue that only the epistemological varieties are sufficient to supplement the doctrine of supervenience so as to generate a non-reductive physicalism.Dynamical cognitive scientists, I argue, face two consequent dilemmas. Weak epistemological emergence is consistent with dynamical cognitive science, but it is not the kind of emergence which counts as non-reductive physicalism, whereas strong epistemological emergence could provide a non-reductive physicalist position, but dynamical cognitive scientists cannot subscribe to it because of the form of explanation they seek and provide. As a result, neither the weak nor the strong version of the intuition is warranted. In responding to this dilemma, dynamicists face another. On the one hand, they can subscribe to what I call "nomological emergence," which preserves the weak intuition at the expense of embracing a kind of mysterianism about the mind. On the other hand, they can subscribe to "functional reductionism," which would amount to abandoning the intuition with which I started. Which of these latter options is preferable, I conclude, is an open empirical question.I go on to distinguish four resulting disagreements amongst supporters of the dynamical approach. Such disagreements might seem to indicate that the dynamical approach is not a single, unified paradigm. What unifies the dynamical approach, however, is a commitment to the same style of explanation. I outline three separate lines of evidence for this claim, all of which support the conclusion that dynamical cognitive science provides (and seeks) covering-law explanations.
