It’s clear that if we use the mind attentively, mental power is increased, and if we concentrate the mind in the moment, it is easier to coordinate mind and body. But in terms of mind and body unity, is there something we can concentrate on that will reliably aid us in discovering this state of coordination? In Japan, and to some degree other Asian countries, people have historically focused mental strength in the hara (abdomen) as a way of realizing their full potential. Japan has traditionally viewed the hara as the vital center of humanity in a manner not dissimilar to the Western view of the heart or brain. I once read that years ago Japanese children were asked to point to the origin of thoughts and feelings. They inevitably pointed toward the abdominal region. When the same question was asked of American children, most pointed at their heads or hearts. Likewise, Japan and the West have commonly held differing views of what is physical power or physical health, with Japan emphasizing the strength of the waist and lower body and Western people admiring upper body power. (Consider the ideal of the sumo wrestler versus the V-shaped Western bodybuilder with a narrow waist and broad shoulders.)However, East and West also hold similar viewpoints regarding the hara, and we’re perhaps not as dissimilar as some might imagine. For instance, hara ga nai hito describes a cowardly person, “a person with no hara.” Sounds similar to our saying that so-and-so “has no guts,” doesn’t it?

Reasonableness is a matter of degree. Beliefs can be very reasonable (Japan exists), fairly reasonable (quarks exist), not unreasonable (there's intelligent life on other planets) or downright unreasonable (fairies exist).There's a scale of reasonableness, if you like, with very reasonable beliefs near the top and deeply unreasonable ones towards the bottom. Notice a belief can be very high up the scale, yet still be open to some doubt. And even when a belief is low down, we can still acknowledge the remote possibility it might be true.How reasonable is the belief that God exists? Atheists typically think it very unreasonable. Very low on the scale. But most religious people say it is at least not unreasonable (have you ever met a Christian who said 'Hey, belief in God is no more reasonable than belief in fairies, but I believe it anyway!'?) They think their belief is at least halfway up the scale of reasonableness.Now, that their belief is downright unreasonable might, in fact, be established empirically. If it turned out that not only is there no good evidence of an all-powerful, all-good God, there's also overwhelming evidence against (from millions of years of unimaginable and pointless animal suffering, including several mass extinctions - to thousands of children being crushed to death or buried alive in Pakistan earthquake, etc. etc. etc.) then it could be empirically confirmed that there's no God.Would this constitute a 'proof' that there's no God? Depends what you mean by 'proof'. Personally I think these sorts of consideration do establish beyond any reasonable doubt that there is no all-powerful all-good God. So we can, in this sense, prove there's no God.Yet all the people quoted in my last blog say you cannot 'scientifically' prove or disprove God's existence. If they mean prove beyond any doubt they are right. But then hardly anything is provable in that sense, not even the non-existence of fairies.
