I regularly get messages from Christians which cover the following ground.
There has to be more to life than this.
I can't believe that the universe could just happen.
Life is too complicated for evolution to be an explanation
Science explains the hows but it says nothing about the whys.
You could put them all together under the general heading: I can't believe it.

All I can say is that I am sympathetic. But the universe isn't. There is no reason why a rational person should expect the truth to feel right. Can you give me a rational explanation for a human ability to instinctively feel the truth of equations, logical arguments or other scientific explanations? We do have an ability to feel ideas, some ideas, this has evolved in the context of social evolution. We can feel when people are lying. Many people are almost as good at this as the finest polygraphs. This ability is perfectly explainable in scientific terms. It is self-evident that an ability to assess who is trustworthy and who is not would be an enormous advantage to any intelligent social being. There is plenty of evidence that the size of social groups is a good predictor of brain size in social animals. Brains can be used to police social exchange, reciprocation, recognition of individuals and their reputation for reliability. The bats with the biggest brains in relation to their bodies are vampire bats, which have an elaborate social system that relies on individual bats being able to recognize other individuals who have co-operated, or not, with them in the past. Vampire bats have big brains because they need to trust other bats and police that trust against freeloaders, vampire bats share food with unrelated individuals, this unusual behaviour requires an unusually well developed brain. Man is a social animal too, that is why we are so smart, social skills made us smart. But only in ways that are of benefit in social situations. We did not develop brains that can naturally understand the properties of substances from their atomic structure or instinctively know whether the Earth moved around the Sun or vice versa. Elephants too have very large brains and elaborate social structures which rely on memory of individuals and the social relationships between them. That is how our brains have developed. By social skills and later by language skills. At no time in our evolution did we gain the ability to perceive truth in the abstract. Such an ability could never evolve. What has happened is that we have co-opted brain structures and patterns of thinking that have served us well in social and linguistic development. Our brains are not evolved to do physics, philosophy, chemistry or theology. We get by. Some people do better than others and so we forget that we are totally second rate at the whole thing. Our ability to do philosophy or theology is spread through the population in a similar way to our ability to do anything else, like run or swim or make music. But just as we are, objectively, rather poor at swimming compared to animals that have evolved in an aquatic environment we are also objectively very poor at philosophy, theology and the art of knowing the truth. If ever anybody says they have difficulty believing a scientific explanation and think that it doesn't feel right I know what they mean. I also know that their feeling and difficulty in grasping a concept is totally irrelevant to the truth or otherwise of that concept. Truth is stranger than fiction

Syntax does not make good sense. Just because a question can be framed does not mean that it should be answered or is capable of an answer. Most of the big why questions are like that. Why is there a universe rather than nothing? It has no answer, it does not deserve one. Just as you can keep asking your calculator to divide one by zero for as long as you want it is not able to give you a satisfying answer. |
Most children go through The Why Stage. My wife has been a nanny to many children in addition to looking after our own two. She is familiar with the problem of the constant but why? questions. Children have to learn that there is a distinction between a good question and a bad one. It is one of the most important lessons any person learns, and I doubt we will ever come across a final definitive answer, a certain way to spot which questions are worth asking and which are dead ends.
I have tried to train my brain to spot good questions as I muse on life. Do starfish have a different sense of geometry and spatial awareness because they have radial symmetry rather than bilateral symmetry? Is there an evolutionary explanation for why men seem to suffer more when they are ill than women do? Is everybody equally conformist, but in different ways? Good questions, which offer up interesting lines of speculation and possibilities for research. In total contrast to "what are we alive for"
Most things do not need an answer or an explanation. Evolution,
for example, needs no explanation. Why do things evolve ask Christians,
it simply shows their total ignorance of the process. If a thing is replicated
with a random incidence of failure (mutation) and not all the copies can
survive there will be evolution, there MUST be; this is as self-evident
as anything in geometry or mathematics. Replication within a finite and
imperfect universe leads to evolution as surely as three equal length
sides on a flat polygon lead to 60 degree angles.
No force could make it otherwise unless that force
could defy logic, in which case all bets are off and you might as well
go mad.
One divided by zero will always yield an error message and questions about the why of physics and cosmology will also yield the same result for similar reasons. This is not a flaw in mathematics or logic or the universe, the flaw is in the human mind.
