How people are like robots
Daniel C. Dennett is the author of Intuition Pumps and Other Tools for Thinking, Breaking the Spell, Freedom Evolves, and Darwin's Dangerous Idea and is University Professor and Austin B. Fletcher Professor of Philosophy, and Co-Director of the Center for Cognitive Studies at Tufts University. He lives with his wife in North Andover, Massachusetts, and has a daughter, a son, and a grandson. He was born in Boston in 1942, the son of a historian by the same name, and received his B.A. in philosophy from Harvard in 1963. He then went to Oxford to work with Gilbert Ryle, under whose supervision he completed the D.Phil. in philosophy in 1965. He taught at U.C. Irvine from 1965 to 1971, when he moved to Tufts, where he has taught ever since, aside from periods visiting at Harvard, Pittsburgh, Oxford, and the École Normale Supérieure in Paris.
His first book, Content and Consciousness, appeared in 1969, followed by Brainstorms (1978), Elbow Room (1984), The Intentional Stance (1987), Consciousness Explained (1991), Darwin's Dangerous Idea (1995), Kinds of Minds (1996), and Brainchildren: A Collection of Essays 1984-1996. Sweet Dreams: Philosophical Obstacles to a Science of Consciousness, was published in 2005. He co-edited The Mind's I with Douglas Hofstadter in 1981 and he is the author of over three hundred scholarly articles on various aspects on the mind, published in journals ranging from Artificial Intelligence and Behavioral and Brain Sciences to Poetics Today and the Journal of Aesthetics and Art Criticism.
Dennett gave the John Locke Lectures at Oxford in 1983, the Gavin David Young Lectures at Adelaide, Australia, in 1985, and the Tanner Lecture at Michigan in 1986, among many others. He has received two Guggenheim Fellowships, a Fulbright Fellowship, and a Fellowship at the Center for Advanced Studies in Behavioral Science. He was elected to the American Academy of Arts and Sciences in 1987.
He was the Co-founder (in 1985) and Co-director of the Curricular Software Studio at Tufts, and has helped to design museum exhibits on computers for the Smithsonian Institution, the Museum of Science in Boston, and the Computer Museum in Boston.
Question: How are people similar to robots?
Daniel Dennett: We’re robots, made of robots, made of robots, made of robots. You’ve got billions, several hundred billion probably cell neurons in your brain. Each one of those neurons is eukaryotic cell with nucleus and with mitochondria and it’s a direct descendant of free swimming, free living autonomous little single celled organisms that have been around for billions of years.
And if you look inside each neuron you find that there are motor proteins in there; little motor proteins are certainly a robot. It’s not alive. It’s a bit of nano-engineering that does all sorts of interesting works, it’s mindless and that’s what we’re made off.
Now, in a way when you think about it, that way you realize how outrageously ambitious it is to make a humanoid robot that has the power of a human brain when the modeling of the individual neurons is extremely crude compared to what the brain can do. The brain has literally trillions and trillions of moving parts. The most elaborate robot yet conceived, and counting the chip as a collection of moving parts, doesn’t have trillions of moving parts. It’s by orders of magnitude simpler.

Universities claim to prepare students for the world. How many actually do it?
- Many university mission statements do not live up to their promise, writes Ben Nelson, founder of Minerva, a university designed to develop intellect over content memorization.
- The core competencies that students need for success—critical thinking, communication, problem solving, and cross-cultural understanding, for example—should be intentionally taught, not left to chance.
- These competencies can be summed up with one word: wisdom. True wisdom is the ability to apply one's knowledge appropriately when faced with novel situations.
SpaceX's momentous Crew Dragon launch is a sign of things to come for the space industry, and humanity's future.
- SpaceX was founded in 2002 and was an industry joke for many years. Eighteen years later, it is the first private company to launch astronauts to the International Space Station.
- SpaceX's Crew Dragon launched NASA astronauts Bob Behnken and Doug Hurley to the ISS at XXXpm today. The journey will take about 19 hours.
- Dylan Taylor, chairman and CEO of Voyager Space Holdings, looks at SpaceX's journey from startup to a commercial space company with the operating power of a nation-state.
A new study may help us better understand how children build social cognition through caregiver interaction.
This is what the world will look like, 250 million years from now
To us humans, the shape and location of oceans and continents seems fixed. But that's only because our lives are so short.
Researchers at UT Southwestern noted a 47 percent increase in blood flow to regions associated with memory.
- Researchers at UT Southwestern observed a stark improvement in memory after cardiovascular exercise.
- The year-long study included 30 seniors who all had some form of memory impairment.
- The group of seniors that only stretched for a year did not fair as well in memory tests.
