A person has a right to believe in a superior being. A person has a right to have faith or hope. It is up to them if they hope that a cure for cancer is found or if they hope they go somewhere nice when they die.
I'd put it this way. We find ourselves alive here on Earth born into a world we must learn to cope with. How well we cope is pretty much a function of what we know vs how ignorant we are. In former times, life was far more treacherous. Society has come a long, long way. Yet, dangers remain.
If we choose to live it then becomes a question of how well we want to do it. How much do we need to create a better life than mere existence? Throughout mankind's history there have been many efforts at discovering the very best way to have a long, happy and self-fulfilling life. Man started with ignorance and imagined how the world worked and we call that SUPERSTITION when it isn't our belief. We call it RELIGION when it is.
The second stage of development was the application of intelligent observation of effects and their causes applying the intellect and curiously seeking answers. This was the age of PHILOSOPHY and none did it better than the Ancient Greeks. As a matter of fact, the stage was set for all that followed. PLATO gave us one set of criteria and ARISTOTLE gave us the other.
Just about everything since Plato and Aristotle has fallen into line with one OR the other.
Plato gave us a Primacy of Consciousness. What is in the mind's eye is more real than what is outside the mind. What we THINK is what is real, according to him. TRUTH is born into us and we must discover it by turning inward. Human senses lie and our perceptions are not to be trusted. Reality is but a distorted mirror of reality.
Aristotle, on the other hand, paved the way for Science. He organized his thinking by applying the greatest tool mankind has ever discovered: LOGIC.
LOGIC is the art of non-contradiction in identifying what exists and how it works and how we may use the knowledge.
Throughout the millennia, either one or the other's thinking held sway. Christianity was built on a solid core of Neo-Platonic philosophy. Science, on the other hand, was founded on the bedrock of Logic and discovery through investigation of natural phenomena.
Think of it this way.
ARISTOTLE investigated how the world works by using his senses and developing conceptual categories. He subdivided categories into definitions. He told us that, in effect, for something to actually exist it must have IDENTITY. It must be "something". The something distinguishes it from all else. The greater the number of descriptions (definitions) you have for your concepts the closer you are to true knowledge of the thing itself. (The identification required PROOF that was solid and demonstrable). Geometry was the first science to demonstrate its proof in a rigorous way. THE ELEMENTS is a book of proofs from about the 4th century B.C.E. which was compiled by EUCLID. It is still valid and can be translated into any language and demonstrated to work harmoniously.)
It is like being a blind person in a world of thorns, thistles and pitfalls who must gradually feel their way carefully around to establish what is there for avoidance (of pain) and benefit (use and comfort.) It can be done, but, it requires intelligent focus and a determination to organize what is known/unknown into useful knowledge.
Religion made wild guesses that created imaginative stories of gods and angels, demons and invisible worlds. There were no blind forces. Humans were insignificant pawns who were fated to some destiny or other under their power of OTHERS.
The only escape for humanity (according to RELIGION) was ritual behavior. Almost always, this required having an enlightened master of some description LAY IT ALL OUT FOR YOU what you must DO and what you must AVOID. It was second-hand information from the horse's mouth, so to speak. (The guru, priest, shaman, witch doctor, prophet who miraculous "knew" all the answers usually earned a pretty good living from this mystical talent :)
Science was discovery the old-fashioned way: experimentation and trial and error.
By starting this thread I meant to shine a bright spotlight on where BOTH processes have led mankind.
When you say a "person has a right to have faith or hope", to my ears you are saying "a wrong guess is as good as an accurate discovery"---and I can't accept that.
I see religious people as being trapped inside very narrow thinking full of fears and taboos who are locked in to rituals and superstitious bargains with invisible friends and foes who control their destiny from afar. I call it INSANITY. You call it a virtue.
