In some areas of cognitive science we are confronted with ultrafast cognition, exquisite context sensitivity, and scale-free variation in measured cognitive activities. To move forward, we suggest a need to embrace this complexity, equipping cognitive science with tools and concepts used in the study of complex dynamical systems. The science of movement coordination has benefited already from this change, successfully circumventing analogous paradoxes by treating human activities as phenomena of self-organization. Therein, action and cognition are seen to be emergent in (...) ultrafast symmetry breaking across the brain and body; exquisitely constituted of the otherwise trivial details of history, context, and environment; and exhibiting the characteristic scale-free signature of self-organization.

This book explains how the Cratylus, Plato's apparently meandering and comical dialogue on the correctness of names, makes serious philosophical progress by its notorious etymological digressions. While still a wild ride through a Heraclitean flood of etymologies which threatens to swamp language altogether, the Cratylus emerges as an astonishingly organized evaluation of the power of words.

We believe the dichotomy of processes introduced in the target article is highly speculative, because the dichotomy is shaped by the questionable assumption of modularity and the complementary assumption of locality. As a result, the author falls into a line of circular reasoning that biases his analysis of the experimental and neuropsychological data, and weakens the proposed model.

Stoffregen & Bardy's primary motivation for rejecting current views on specification in favor of the global array is that current forms of specification in single-energy arrays allow the ambiguous or inadequate specification of reality. I show that this motivation is not justified, and that the global array concept still falls prey to inadequate specification.
