But the questions Horgan raised refused to go away. Now, an internationally known leader in science has leapt into the fray. The subject recently spilled over onto the pages of The New York Times , where Maddox and Horgan met in a headstrong clash. We know when life began on Earth, but we don't know how. We are just now beginning to get a hold on genetics.
Scientific discovery is roughly comparable to the discovery of the Earth.
The more we know about the Earth, the less there is to discover. We have mapped out all the continents, and oceans, and mountain ranges, and rivers. We are down to details now. Give Horgan credit for guts. It takes a lot of intestinal fortitude to argue that we already know so much that we're not likely to be very surprised by anything we learn in the future.
