Where Did Our Language Come From

The Motor Theory of Language Origin

The motor theory is about the process by which language emerged and developed and how it functions now in human speech. The concern is with both synchronic and the diachronic aspects of language, language evolving over time and differentiating over space. In English alone we have half a million words and endless syntatic complexities, as Chomsky has demonstrated. Add the multitude of other languages that exist and have existed and it is apparent that language is a massive multiply-faceted fact-in time and space. Where did all the complexity come from? Whence the power of words seen in so many diverse forms of human interaction? How does this thread of sound tie our minds together?

Wittgenstein, Finitism, and the Foundations of Mathematics

Mathieu Marion offers a careful, historically informed study of Wittgenstein's philosophy of mathematics. This area of his work has frequently been undervalued by Wittgenstein specialists and by philosophers of mathematics alike; but the surprising fact that he wrote more on this subject than on any other indicates its centrality in his thought. Marion traces the development of Wittgenstein's thinking in the context of the mathematical and philosophical work of the times, to make coherent sense of ideas that have too often been misunderstood because they have been presented in a disjointed and incomplete way. In particular, he illuminates the work of the neglected 'transitional period' between the Tractatus and the Investigations. Marion shows that study of Wittgenstein's writings on mathematics is essential to a proper understanding of his philosophy; and he also demonstrates that it has much to contribute to current debates about the foundations of mathematics.
