Do you believe in life after death?
The belief that there is some form of "life" after death is human hubris at its worst. It's the conviction that of all the gazillions of tons of matter in the universe, these particular hunks of organic tissue are
so fucking special that we not only evolved intelligence like many animals and language skills like a few of them, but we, alone, evolved something that completely
falsifies science: a soul--a supernatural force that interacts with the natural universe. If this were true it would violate the fundamental principle underlying all science, that the natural universe is a closed system. Understandably, there is absolutely zero evidence that such a bizarre anomaly is true, but that doesn't stop people from embracing the cognitive dissonance of believing it anyway. Because of their
human hubris. "We're so important that the natural laws of the universe don't apply to us." Yeah right!
Please describe exactly what you think happens after we die, and explain why you believe that.
A satisfactory definition of "death" in one of the higher vertebrates (birds and mammals) is the irreversible degradation of the synapses in the brain. So what happens after a person dies is exactly that: His brain loses its electrochemical organization, so everything that comprised his identity--his thoughts, memories, personality, etc.--ceases to exist. If he wasn't killed by an explosion or falling into a vat of acid his body still exists and we might even be able to keep the lower animal functions operating like breathing, heartbeat and metabolism of nutrients. But that's just a pile of organic tissue that has irretrievably lost its higher organization; the
person does not exist any more. His
spirit still exists, according to a sensible definition of the term, because he's left his mark on civilization: the memories of those who loved him and those he taught, the things he built, the ideas he promoted, the attitudes of his children, the success of his business. But the word "spirit" is a metaphor, nothing more. The actual person is simply gone.
Why do I "believe" this? That's a strange question to ask, because it's really a dishonest way of asking why I do not "believe" the mythologies of the religionists. No one has to defend his lack of belief in someone else's fantasies. The burden of proof is on them to explain why it's not completely unreasonable of them to "believe" in it.
In fact, Carl Jung helped us understand why so many people "believe" in things for which there is absolutely no evidence. These things are called "archetypes" and they are instinctive motifs that are pre-programmed into our brains through evolution. They may have been survival traits in an era whose dangers we can't imagine--many archetypes are, such as our instinctive fear of a large animal with both eyes in front of its face, or of stepping off of a precipice; people without those fears didn't live long enough to reproduce. Or they may be accidents passed down through a genetic bottleneck like Mitochondrial Eve. In any case, since we're born with these beliefs they
feel true, and that makes them seem more true than the beliefs we acquire later in life through learning and reasoning.
Please also say whether you consider yourself religious or a believer in God or the supernatural.
I do not "believe" in gods or any other supernatural things. We have spent five hundred years, since the initial development of the scientific method, exhaustively testing the basic hypothesis that the natural universe is a closed system whose behavior can be predicted by theories derived logically from empirical observation of its present and past behavior. That hypothesis has never been falsified, so it now stands as the canonical theory that underlies all science--"true beyond a reasonable doubt," to borrow the language of the law since the language of science sucks when attempting to communicate with laymen.
Any hypothesis that contradicts a canonical theory is by its very nature an extraordinary hypothesis, and according to the Rule of Laplace--another key component of the scientific method--it must be accompanied by extraordinary evidence before we are obliged to treat it with respect. No extraordinary evidence for the existence of a supernatural universe and supernatural creatures that interact with the natural universe has ever been provided. In fact there has never been a shred of evidence that could even be regarded as promising, worth a second look. Millions of scientists lead second lives as religionists when they take their lab coats off, and none of them has ever run back into the lab the next morning with the evidence he needs to resolve his cognitive dissonance regarding the nature of the universe.
Beliefs in the supernatural are based entirely on hope, instinct, and human hubris. We are therefore under no obligation to treat them with respect, at least in a place of science like this one. Of course that doesn't mean we are obligated to treat them with disrespect, but a few of us do.
Civilization and its precursor, the Agricultural Revolution, has been an eleven-thousand-year struggle to override our Stone Age instincts with reasoned and learned behavior. It's long past the time to override the instinct to believe in supernatural creatures, since it has stalled civilization at the level of hostile tribes making war on each other over their different interpretations of the archetype of "God."
