I don’t believe I can let this subject pass by leaving my own conflicted emotions unconfessed. When Carl Sagan won the Pulitzer Prize for nonfiction … - Edward O. Wilson

"Would I be happy if I discovered that I could go to heaven forever? And the answer is no. Consider this argument. Think about what is forever. And think about the fact that the human mind, the entire human being, is built to last a certain period of time. Our programmed hormonal systems, the way we learn, the way we settle upon beliefs, and the way we love are all temporary. Because we go through a life's cycle. Now, if we were to be plucked out at the age of 12 or 56 or whenever, and taken up and told, "Now you will continue your existence as you are. We're not going to blot out your memories. We're not going to diminish your desires." You will exist in a state of bliss - whatever that is - forever. [...] Now think, a trillion times a trillion years. Enough time for universes like this one to be born, explode, form countless star systems and planets, then fade away to entropy. You will sit there watching this happen millions and millions of times and that will be just the beginning of the eternity that you've been consigned to bliss in this existence."

I don’t believe it too harsh to say that the history of philosophy when boiled down consists mostly of failed models of the brain. A few of the modern neurophilosophers such as Patricia Churchland and Daniel Dennett have made a splendid effort to interpret the findings of neuroscience research as these become available. They have helped others to understand, for example, the ancillary nature of morality and rational thought. Others, especially those of poststructuralist bent, are more retrograde. They doubt that the “reductionist” or “objectivist” program of the brain researchers will ever succeed in explaining the core of consciousness. Even if it has a material basis, subjectivity in this view is beyond the reach of science. To make their argument, the mysterians (as they are sometimes called) point to the qualia, the subtle, almost inexpressible feelings we experience about sensory input. For example, “red” we know from physics, but what are the deeper sensations of “redness”? So what can the scientists ever hope to tell us in larger scale about free will, or about the soul, which for religious thinkers at least is the ultimate of ineffability?

the great majority of people worldwide remain in the thrall of tribal organized religions, led by men who claim supernatural power in order to compete for the obedience and resources of the faithful. We are addicted to tribal conflict, which is harmless and entertaining if sublimated into team sports, but deadly when expressed as real-world ethnic, religious, and ideological struggles. There are other hereditary biases. Too paralyzed with self-absorption to protect the rest of life, we continue to tear down the natural environment, our species’ irreplaceable and most precious heritage. And it is still taboo to bring up population policies aiming for an optimum people density, geographic distribution, and age distribution.
