In this RI Lecture, Daniel Dennett explores the first steps towards a unified theory of information, through common threads in the convergence of evolution, learning, and engineering. The concept of information is fundamental to all areas of science, and ubiquitous in daily life in the Internet Age. However, it is still not well understood despite being recognised for more than 40 years. In this talk, Daniel Dennett explores steps towards a unified theory of information, through common threads in evolution, learning, and engineering. This event was the first in a series on the theme of ‘Convergence’, exploring the links between neuroscience, philosophy and artificial intelligence. Daniel Dennett is known as one the most important philosophers of our time, with controversial and thought-provoking arguments about human consciousness, free will, and human evolution. He is also a writer and cognitive scientist, using neuroscience, linguistics, artificial intelligence, computer science, and psychology to inform his philosophy, particularly his philosophies relating to evolutionary biology and cognitive science.
