Since its inception in the early 20th century, neuroscience has taught us a tremendous amount about the brain. But if neuroscientists want to understand the mystery of consciousness, they'll need new methods.

The success of modern neuroscience represents the triumph of a method: reductionism. The premise of reductionism is that the best way to solve a complex problem -- and the brain is the most complicated object in the known universe -- is to study its most basic parts. The mind, in other words, is just a particular trick of matter, reducible to the callous laws of physics.

But the reductionist method, although undeniably successful, has very real limitations. Not everything benefits from being broken down into tiny pieces. Look, for example, at a Beethoven symphony. If the music is reduced to wavelengths of vibrating air -- the simple sum of its physics -- we actually understand less about the music. The intangible beauty, the visceral emotion, the entire reason we listen in the first place -- all is lost when the sound is reduced into its most elemental details. In other words, reductionism can leave out a lot of reality.
