What you are insisting upon is that that consciousness absolutely cannot be explained by science, yet you have provided no evidence for this. This is a very different claim from insisting that there exist unprovable statements in science.
OK, I will repeat once again:
We look at the statement 'All there is to the world can be derived from science'. This is the basis for the scientific-positivistic world view (Sagan, Dawkins, Hawking, Atkins, etc.).
If this statement is made from within science, it is completely meaningless. This is because, a pure scientist must reduce this statement to: 'All there is to the scientific aspects of the world can be derived from science', which is self-evident and therefore redundant.
In order for the original statement to have any meaning at all, it must therefore be made from without science. This means, a scientist who makes such a statement automatically becomes a philosopher - he must derive this statement from without science. Thus, we have created at least one statement about the world, which cannot be derived from science. Therefore it is self-contradictory and therefore false.
You can easily apply the same argument to the statement 'All there is to consciousness can be derived from science'. Scientifically, the statement must be reduced to: 'All there is to the scientific aspects of consciousness can be derived from science' -> redundant. To make it non-redundant, it is necessary to derive this statement from without science. Now we have created a statement about consciousness, which is not derived from science -> self-contradictory -> false.
Please tell me exactly where in this simple argument I insist on anything other than pure simple logic.
Please tell me exactly why you say I provide no evidence. Isn't simple logic evidence enough?
Please tell me where in this argument I talk about 'unprovable statements in science'?
This simple argument remains unchallenged in this whole thread. It requires no believe, faith, or insistence at all, just a little logic comprehension.
Science is a modeling language and it's a predictive language. We believe in the theory of gravity because our model allows us to make incredibly accurate predictions about the nature and affects of this invisible force. It is not the same as an invisible dragon -- which has no affect on the outside world, nor whose behavior can be understood or predicted via scientific modeling. Do you see the difference?
What you describe here is exactly the reason why inaccuracy leads to obsolete quarrels between philosophers/theologists and scientists. There are two sides of this argument. One is the scientific side and one is the philosophic side:
A) Scientific side:
We have the theory of gravity. If we stay within the scientific realm, all we have is a mathematical formula and scientific observations. As long as our scientific observations match the formula, the scientific theory holds true. That's it. In the mathematical formula, you will not find an actual 'force field'. The formula just predicts the motion of objects (resp. the force needed to stop them from moving).
A scientist tries to
explain the theory of gravity by saying there is an 'invisible force field'. This is tricky. As long as he knows that he just uses the term 'force field' as a synonym for the mathematical formula - without an actual imagination of a real, mysterious, invisible field of force behind it - this is still fine. In this case he can still claim to remain within the realm of science. Of course, he doesn't really provide an
explanation, just a different name for the formula.
B) Philosophic side:
The error of Sagan is that he must already imagine such a real field of force behind the theory of gravity
to be able to compare it to the imagination of a real invisible dragon. Both theories are not scientific theories anymore, since they are made up by the mind as
possible reasons for the scientific theory. The theory of the invisible dragon is not a competition to the scientific theory of gravity (the formula). Rather, the invisible dragon is competition to the philosophic theory of the invisible force-field.
Again, the simple thought experiment: Imagine that there are invisible dragons that somehow manage to move objects exactly in the way, the formula of gravitation predicts. For science it is impossible to determine whether the imagination of the mysterious force field or the imagaination of the invisible dragons is more valuable. Science is not concerned with it at all. There is no scientific evidence that would support one or the other philosophic theory.
That's why articles like the one from Sagan must be dismissed as pseudo-philosphy. He thinks he is still argueing from within science when in fact he must have already left the realm of science to write such an article. What slips his mind is the necessary step from the pure scientific theory to the imaginary explanation which is already outside of science.
