It seems to me that you are of the belief that you can rely upon science to answer all of life's questions and that there is no need and has never been a need for religion.
Science doesn't really so much answer life's questions as it measures things and allows predictability into choices about process. There is no need for religion because it is an "I want" situation. For example, "I want to live forever and the only way I can is to postulate somebody who can make that happen." Consequently, God is invented.
A mature person (ahem) knows the difference between "I want" and "I need".
Humanity needs information which is clear, transparent and accurate because our decisions become fine-tuned by the level of accuracy in our premises and choices.
You have to admit that there are alot of questions that science can't answer, for example, there are certain diseases for which there is currently is no cure. When this happens there has to be a benefit to some people for the comfort they receive through their religious beliefs.
If we refuse to be realistic about life we force ourselves to cope with unpleasant reality by wishing it away or not paying attention to the consequences and pretending there are none. Religion has the same comfort quotient as lying.
Scenario Number 1:
Doctor: Mr. Jones you are going to die of cancer.
Jones: Oh, no!! Oh, nooo! Oh, Noooooooo. This is terrible. Wahhhhhhhhhh.!
Scenario Number 2:
Doctor: Mr. Jones you are NOT dying of cancer, but, you are feeling ill. It will probably pass eventually. Cheer up!
Jones: Oh thank you, Doctor! I feel so much better!
Scenario Number 3:
Doctor: Mr. Jones, you are dying of cancer. There is nothing science or medicine can do for you. Shall I call a priest?
Jones: Yes!
Priest: Don't worry, brother Jones. God will forgive all your sins and you will spend eternity in heavenly bliss. This life is but a shadow. Pray with me now.
Jones: Oh thank you, Father, thank you. I feel so much better........
Because when you get down to it, we are not totally logical beings.
This is a choice some people make. It is a terrible choice. Logic is a tool for removing contradiction between links in our chain of understanding.
When we tolerate contradiction we choose lies, misinformation, disinformation, false choices.
A more accurate way to say what you said would be to say this: Humans have a low tolerance for unpleasant facts and often decide to ignore them by pretending there are "higher" facts which nullify the consequences.
It all comes down to how frank and honest we are with our own self.
mankind does not always act in a logical fashion controlled by reason. We have emotions and feelings
Our emotions (and feelings) come directly from the values we hold. Our values come from CONSCIOUS evaluation if we are rational. If we decide to be lazy or to ignore reality our values come from the default setting: folk tales, rumors, opinions, wishful-thinking, etc. Our EMOTIONS are involuntary but the values that create those emotions are not---UNLESS we make them that way through default.
People who seem to be controlled by their emotions are really controlled by their values which are hidden to them because they refuse to actively participate in forming detailed, proven, opinions based on non-contradictory information.
There have been many times throughout history where man has decided that they knew it all and that science had answered the questions only to find out that there was more to learn and despite all of advances of science, both good and bad, religion and a belief in a Supreme being has survived
Scientific Methods make an effort to refute currently held theories. Science is therefore subject to disproof on purpose. God cannot be proved because imaginary persons are not subject to experiment or demonstrations.
America did drop the atomic bomb under the logic that it would save more American lives than an assault on Japan. In otherwords, because of the practical notion of our survival we used our technological advantage to destroy a weaker enemy. Sounds exactly like your definition of the benefit of science.
America wanted to scare the Soviet Union because we knew we'd have to fight them next. The Army desperately wanted to avoid an all out assault on the mainland of Japan. If you stop and think about it from a practical standpoint--it is no worse to kill thousands of people with a Tomahawk than it is with a gun or a bomb. It just SEEMS far worse because it is so quick and powerful. Killing is killing and war is war; both are immune to technology as far as motivation.
Sounds exactly like your definition of the benefit of science.
I can remove the plastic from a loaf of bread and smother somebody to death by putting the bag over their head. Is the Wonder Bread company to be held an accessory to murder???
