Because the Darwinists;
- have destroyed knowledge about freedom, the future, time, decisions, God, right and wrong, intelligence, design, Aristotle's final cause
- destroy all ways of knowing that is not by the scientific method, including reasonability, common knowledge, religion
- make the scientific method repulsive to everybody by overselling it
The majority of scientists in the world do not believe freedom is real, and a great share of them actively and openly destroys any and all knowledge about it, trying to fit everything into a cause and effect paradigm. It is particularly Darwinists who do this, because the theory of natural selection is used to replace the concept of choosing with.
For those who still listen to reason; denying freedom is out of bounds of reasonability, in most all situations, in most all places in the intellectual landscape. The denial is an extremist position, and the deniers show themselves to be extremists in many areas of intellect besides this particular area.
It is not acceptable if your knowledge about decisionmaking is limited to the options of a) random b) brain-intelligence. Then you are stupid. A reasonable guess would be that there are approximately 10 ^9999 ways of making decisions, and not just 2.
So please, show some intelligence and acknowledge some intelligent design. Acknowledge something in between randomness and human intelligence, and above all acknowledge all choosing as fundamentally free, and thus spiritual.
