The title of this post is a quote from Ernest Hemingway. It evokes a sense of personal conscience. If you perform some act and then feel a sense of regret afterwards, chances are what you did is not in line with what you believe is moral. Contrariwise, if something you do leads to a feeling of accomplishment or if it somehow enhances your self worth, the act was probably moral to you.
But is it possible for two different people to complete the exact same action or set of actions and come away with opposite feelings about having done it? The answer, of course, is yes. Consider this example: A young man who was raised Baptist goes on his first date with a girl he met in church. She is very attractive and very sexy. She also is very open about her sexuality and convinces the young man that’s she is ok about having sex with him, even though it is only their first date. He initially resists, but his hormones kick in and minutes later, the deed is done. Afterward, he feels intense guilt. He feels dirty and even betrayed. He vows not to give in to temptations of the flesh again.
Compare that with another scenario: A young man who was raised by freethinkers decides to attend a Baptist church service with his Christian friends. While there he meets a very pretty girl. They hit it off and he asks her out on a date. She accepts and the next night they go out. Afterward, she lets the young man know that she is ok with it if he wants to have sex with her. They do the deed and afterward they feel spent but happy. They each have found a new friend and both agree to get together a second time.
In the first example, the young man felt guilty because he broke his moral code. In the second example, there was no guilt, because the young man’s moral code did not include having sex outside of marriage. Therefore, he felt good afterward.
At this point the Christian (at least the fundamentalist Christian) will say the first young man should have felt guilty because he violated God’s moral code. The freethinker might counter that since God does not exist, the Christian’s moral code is based on a faulty premise. But since neither side can prove their premise, one side’s moral code is no better than the other’s. In such a situation, it would be inappropriate for one side to restrict the behavior of the other side based on their own view of what is moral.
So what should we base our moral code on? According to Christians, the bible is important for morality because we need a basis by which to judge what is right and wrong and the bible provides that basis. Without it, they claim, any act can be rationalized as moral.
But why does it have to be the bible? If we do need a benchmark for morality, why do we need to pick something that not everyone agrees is valid? Isn’t there a more universal benchmark we could use?
As it turns out, there is. Morality is simply a set of codes that direct behavior. In a social species, such as humans, it is important for individuals to behave properly when interacting with other individuals. Individuals who behave badly are often shunned by the group and do not get to participate in activities such as hunting or feeding rituals, which means that in harsh times, those who are shunned may actually perish because no one will help them through. In essence, then, good behavior is evolutionarily selected for and bad behavior is selected against.
What behaviors are selected against? Those behaviors that tend to diminish cooperation in a society or behaviors that tend to favor the individual over the group are probably marked for elimination. In a social species, behaviors that enrich the society, or at least those that do not diminish society, tend to be favored.
Taking a page from natural selection’s how-to manual, we can apply that same sort of criteria for determining what is moral and what is not. Morality is simply a code of behavior that limits a person’s actions to behaviors that are not detrimental to society as a whole. Prohibited behaviors, those that tend to disrupt or harm society, will be actions such as murder, rape, theft, perjury, embezzlement, assault, battery, or child molestation. The prohibition on less heinous behaviors must be weighed against the limitations on personal liberty and personal privacy that we all cherish. So we can debate whether or not something like public drunkenness should be a crime, or whether that decision should be based on connected behaviors.
But behaviors such as having sex outside of marriage, paying for sex, marrying more than one person, gambling, having an abortion, or marrying someone of the same sex should never be banned by law based on morality because reasonable people will disagree on whether or not they are harmful to society. There might be many reasons to believe that in certain cases, not having an abortion would be more of an encumbrance to society. There might be evidence to support the notion that gambling helps the economy and is thus good for society. There might be reasons to think that having sex with someone to whom you are not married is none of anyone else’s business. And there might be reasons to believe that allowing two people of the same sex to marry will not bring irreparable harm to society but instead make it more tolerant.
The majority religion in this country is Christian. But not even all Christians share the same moral code, because the bible can be interpreted many different ways. But even if all Christians agreed, that would be no excuse for restricting the liberties of those who are not in the majority. The Constitution was set up to protect minority interests from the oppression of the majority.
Having a set of moral principals based on a belief of what is good for society and not on what is found in an ancient text does not in any way prohibit individuals, families, or social cliques from restricting their own behavior further. If a family believes that having sex before marriage is wrong, then members of that family should refrain from doing it. Similarly, if a pregnant woman believes that abortion is a sin, then she should decide not to have an abortion. If a church group believes that gambling is sinful, then the congregation should avoid that activity. But no individual, no family, or no group should ever have enough power to restrict the behavior of others based on the more narrow morality of those who are offended. The Constitution does not provide anyone the right not to be offended. If some behavior offends you then avoid it, but don’t prohibit it. What offends you might uplift someone else. If after performing an action you don’t feel good about it then don’t do it again. But don’t prevent someone else from doing it, because they may feel differently.
Isaac Asimov once wrote, “Never let your sense of morals prevent you from doing what is right.” It’s good advice. I would just add don’t let your sense of morals prevent others from doing what they think is right, too.

Can there be Consciousness after Death?
I often ruminate on matters of the conscious mind. I find the topic fascinating. Another topic I find fascinating is the belief in a god and existence after death. As anyone knows who has read my blog, I'm not a believer in God, especially the personal god of the bible or any other holy book. But I can't rule out with 100-percent assuredness the existence of some kind of entity that could be called God.
If there is any kind of meaningful existence beyond death, it has to be tied to what we call consciousness. Without consciousness, any existence after death would be pointless, even meaningless. So what is consciousness anyway? We can describe it, but can we really define it? Consciousness has a certain ineffable quality that prevents an easy definition. We know what it is, but we don't know how to define it in any satisfying manner.
At its base consciousness is the ability to perceive with the senses and then to act upon those perceptions. It is the ability to think and understand and to control those thoughts, as opposed to the unconscious or subconscious dream state. While that is at least partially a description of what the conscious mind is, it certainly isn't a very satisfactory one. There are lots of questions that need to be answered. In what part of the brain does consciousness reside? What is the brain doing that results in consciousness? Will it ever be possible to create consciousness in a computer or robot? Even if it is one day possible to replicate a human brain can someone's consciousness be downloaded into it? And if so, can it be done in a way that will transfer consciousness, thus allowing for the body to be discarded, or will it merely be a copy of the conscious mind with the original still intact? These are questions I would really like the answers to.
Science does not have a completely cogent theory on consciousness yet. It has been the subject of philosophical debates for centuries. Is there a dual nature to the mind allowing for one part to be composed of matter and the other part to be spiritual, or non-matter? And is it possible for the non-matter part of the mind, the consciousness, to live on after the brain is dead? Medical science seems to answer that in the negative. The brain is made of cells and if deprived of oxygen long enough, the cells die and all activities associated with the cells die with them.
But what if consciousness has a component that is not dependent upon living matter? It might not actually be spiritual or supernatural. It might be something that is perfectly natural and explainable, but something that just hasn't been explained yet.
There is a world of science in which physics and neurology overlap. Granted, it's not a major course of study in most medical schools. Nevertheless, there are some scientists who have posited a hypothesis that might help to explain consciousness without evoking the spiritual. It involves the strange world of quantum mechanics.
Ever since Isaac Newton developed his laws of motion, philosophers and some scientists have been pondering the notion of free will. If Newton's equations can solve the path of a cannonball in flight could it also, in theory at least, solve equations that would predict thought processes within the brain? After all, the brain is just chemistry and physics - moving atoms that have a projectile of their own. If we had enough data about the speed and location of every atom in our brain, wouldn't we be able to predict where they would be in a year, or 10 years? And if thought process are controlled by these particles, then might we not have free will, since each atom, once set into motion, would have no choice but to follow its prescribed path as predicted by the math?
But then, in the 20th century, quantum mechanics came along and rescued free will, sort of. It all started with Werner Heisenberg and his Uncertainty Principle. It states that you can never know the precise location and momentum of any subatomic particle with precision. If you know the location precisely you can say nothing about its momentum, and vice versa. Or you can know a little about both quantities. This is a limitation in principle, not in the equipment. No matter how good the equipment will ever get, the limitation will persist. Think of it this way, if you want to measure the temperature of a cup of hot coffee, you could stick in a thermometer. But in the act of measuring the temperature, the cooler thermometer will affect the temperature of the coffee, so what you end up getting is an average. Since the thermometer is much less massive than the coffee and has a much lower specific heat, the effect will not be great. But what if the cup of coffee was a tiny one, say only a few drops? Then the temperature of the thermometer would make a huge difference and it would not be possible to measure the temperature of the coffee itself. So the act of observation will always affect the quantity being measured.
What does all that have to do with brain cells and conscious thought? Well, in the brain, it has been known for some time that the synapses, the small gaps that connect neurons, are the locations where thought processes occur and memories are stored. But neurons are made of atoms, like everything else, and atoms are made of subatomic particles which follow the laws of quantum mechanics. Because of the Uncertainty Principle, the exact locations of these particles can never be known for sure. For that reason, their paths cannot be predicted with Newtonian physics and, thus, free will is intact. What is known, however, is that they follow the rules of probability. They behave randomly within certain constraints, and those constraints involve the length of the quantum wave function. According to quantum theory, a particle is not really a particle at all until such time as it is observed. Once it is observed in some way, the wave function collapses and the particle materializes. But it can materialize anywhere within the scope of its wave function.
For macroscopic objects, such as a football, the wave function is much tinier than the ball, so a thrown football always appears to follow Newtonian mechanics, and passes are caught. But if the football (and the receiver) were to shrink down to the size of an electron, all bets are off. When the receiver looks back over his shoulder to catch it, it will materialize into a ball, but it could be anywhere within the stadium, or even outside the stadium. The probability of it materializing far away is small, but finite.
Researchers have performed experiments using imaging technology on people's brains that indicate a reaction can occur to a certain stimulus that is on the opposite hemisphere of where the stimulus occurred. And it's an instant reaction. The neurons are not directly connected. So what causes the stimulation? They suspect it might be something called quantum entanglement. In quantum theory, it is possible for two paired particles to send information to each other, even if they are very far apart. And the information sent is not bound by the speed of light. Einstein called the phenomenon "spooky action at a distance." Some scientists speculate that this could be the root of consciousness.
If quantum entanglement can act at distances within the brain, there is nothing in quantum theory that would prevent this sort of action at greater distances, outside the brain. This neurological quantum entanglement might be responsible for the out-of-body experiences some people claim to have had, especially during a near-death event. Taking it to the extreme, some could also speculate that this quantum entanglement could exist well beyond death, and at cosmic distances, since subatomic particles do not rely on a beating heart for their existence. The consciousness that was trapped within the brain while someone is alive might be free to float freely through the universe, as sort of a unified cosmic consciousness after death.
Keep in mind this is all highly speculative, but it is within the realm of science to explore. It also means that it might one day prove plausible as an explanation for some kind of conscious existence after the death of the brain. And it also does not rely on a supernatural god.

Why Do I Bother?
I have written in this blog for years, making what I believe are cogent, logically-consistent, and rational arguments against religion, and especially fundamentalist religions. I've posted the same reasonable arguments on forums and on Facebook. And it always seems that no matter what I say or how well I seem to have made my point, I get replies from those who just don't seem to understand my point at all, or who just reject it out of hand with no valid rebuttal.
And I have been asked on many occasions why I bother. I'm obviously not changing any minds. Those who believe have been brainwashed and deluded and they deny the facts and evidence against them, or they twist it around to make it better fit their dogma. So what's the point? Why do I continue to harp on the fundamentalists?
There is more than one answer. For one thing, I do enjoy a good debate; it helps to strengthen my mental faculties. It's a way to exercise the mind. But that only happens when the ones I'm debating make valid rebuttals - points to actually ponder and then try to refute. That kind of response almost never happens. Blind faith and delusion are all I get in return.
The main reason I continue to post my blog entries and reply on the forums is that I know that there are those out there who are just taking in all the arguments. They don't comment and they don't reply to posts. They just read. I know this because several of them have put in friends requests on Facebook and I don't recognize their names from any forum. They've just been "listening." Sometimes they will comment in their friend request, so I know they have paid attention to my points and that those points have resonated in their minds. And that is why I continue to write and make my case against religion, particularly fundamentalist Christianity. Islam is probably the most dangerous religion on Earth today and many of its adherents are the most highly deluded. But I come from a Christian background and there are many more Christians in this country than Muslims. So I mainly stick to debunking the Christians.
And to those who are among the fence sitters when it comes to faith or to those Christians who have become disillusioned with your faith, take heart. There are lots of you out there. My advice, as always, is simply to listen to the rational part of your brain. It's not the devil; he doesn't exist. It's not your conscience. It's simply common sense knocking. Let it in.
