A treasure of ideas from 108 of our most creative minds - Rated 
(Plus Richard Dawkins, who writes an Afterword.)
I'll give you some dangerous ideas. Take steps to reduce the human population worldwide to around a billion people and keep it there. Take the biological desire of people to play house and be mothers and fathers, and redirect it into responsible stewardship of the planet.
Don't like that one? Seems too draconian? How about this? End all tax exempt status for churches, mosques, etc. (Resounding voice coming onstage: "Only when they tear my cold, dead fingers from the collection plate!")
Here's another: realize that to know all is to forgive all, and that we are all just biological automations acting out our genetic drives and have no more free will than an ant on the pheromone trail. Deal with people acting in antisocial ways by (1) curing them with psychopharmacology, surgery, retraining, or (2) euthanasia.
Decriminalize street drug use. Allow Phillip Morris to get into the cannabis business and Merck to process opium into heroin. If some people become dysfunctional, see previous dangerous idea and employ it.
Well, none of John Brockman's esteemed contributors came up with anything quite THAT dangerous, probably because the danger of such ideas is most immediately to the person who would advance them! Psychiatrist Randolph M. Nesse gives us some guidance on why such ideas are not being advanced in this book in his modest essay on "Unspeakable Ideas." (pp. 193-195) Here's one: "when your business group is trying to deal with a savvy competitor, say, `It seems to me that their product is superior, because they are smarter than we are.'" Also unspeakable is, "I will only do what benefits me." Nesse writes that saying something like that is akin to committing "social suicide."
David Lykken thinks that parents ought to be required to get licenses to parent and prove they are twenty-one years old, married, and self-supporting. (pp. 175-176)
Jordan Pollack urges us (tongue in cheek, I presume) to embrace "faith-based science." He writes, "physics could sing the psalm that perpetual motion would solve the energy crisis..." with God "on our side to repeal the second law of thermodynamics!" "Astronomy could embrace astrology and do grassroots PR with daily horoscopes to gain mass support for a new space program." (pp. 156-158)
John Allen Paulos joins the Buddha and David Hume and presents the self as "an ever-changing collection of beliefs, perceptions, and attitudes, that is not an essential and persistent entity but a conceptual chimera." (p. 152)
Some of the other "dangerous ideas" concern such things as science versus religion (e.g., Sam Harris's "Science Must Destroy Religion" and Philip W. Anderson's "The Posterior Probability of Any Particular God Is Pretty Small"); exciting speculations (Terrence Sejnowski's "When Will the Internet Become Aware of Itself?"), cosmological conjectures (Brian Greene's "The Multiverse," and Leonard Susskind's "The `Landscape'").
Some of the ideas are not dangerous at all of course, and some are only dangerous to certain segments of society. The idea that the Christian God does not exist is no skin off my teeth and no Buddhist feels threatened by it, but television evangelicals find it downright scary. Judith Rich Harris advances the idea that parents really don't shape their children's morays (their peers and the larger society does). This idea isn't threatening at all unless you are a Pygmalion sort of parent infused with a weighty sense of responsibility, and in that case, her idea can help you to chill out.
Some other ideas may or may not be seen as dangerous. Karl Sabbagh suggests that "The Human Brain Will Never Understand the Universe," and Lawrence M. Krauss wants us to know that "The World May Be Fundamentally Inexplicable." Personally I think they're both right, but that shouldn't keep us from trying to expand the range of our knowledge and understanding. Seth Lloyd even goes so far as to suggest that one of our ideas "is likely to have the unintended consequence of destroying everything we know." He adds that "we cannot stop creating and exploring new ideas. The genie of ingenuity is out of the bottle. To suppress the power of ideas will hasten catastrophe, not avert it." (p. 101)
There are several essays on how drugs might, can, and will affect us (e.g., "Drugs May Change the Patterns of Human Love" by Helen Fisher, and "Using Medications to Change Personality" by Samuel Barondes). There are essays on politics and economics (e.g., Michael Shermer's ode to fiscal conservative and social liberalism, "Where Goods Cross Frontiers, Armies Won't" and Matt Ridley's "Government Is the Problem, Not the Solution"), and on the dangers and promises of futuristic technologies by Ray Kurzweil, Freeman J. Dyson and others. In fact there is so much in this book that a reader could study the ideas for decades--seriously--and hardly scratch the surface of what is implied, hoped for, dreamed of, and feared. It is a great collection of ideas, a masterful work of compilation and editing by science's most talented and creative editor, John Brockman. Don't miss this book. It's even better than Brockman's previous collection "What We Believe But Cannot Prove."
Let me throw in one more dangerous idea not in the book (lest I wax too sanguine): suppose that by bioengineering violent aggression out of the human genome (which seems like a good idea) we end up with something like H.G. Wells' Eloi? Can it be true that humans must be violently aggressive, and if not, will become stagnant and exploitable? One might argue that there would then be no exploiter, but should one appear what would--could--we do?
really good read - Rated
