Humans are rational animals.
Most vertebrates are rational and intentional. They’re not as developed, specialized or powerful as humans in many areas but they certain do form plans, have ideas, think about things and engage in purposeful action. As John Searle has said, it is exacltly the same thing for my dog to think someone is at a door as it is for me to think someone is at the door. The fact that I have more complicated and specialized additional concepts tied into someone being at the door is because I am smarter and evolved for human society, but that is a difference of degree and not of kind.
Blue Jays can do math, for Christ’s sake. What an ignorant, pre-critical mythology you ascribe to.
Rationality includes free will and conscious knowledge, which are not scientific concepts.
Rationality does not entail ‘free will’ (whatever the Hell that is supposed to mean) any more than it entails squared circles. In fact these are contradictions. Rationality includes awareness of environment, which is at least partly a product of recursive pattern systems in the brain and is, in any case, a causal product of the material structure of our bodies. Conscious knowledge is a perfectly scientific concept, both in the ontic and logical senses; try reading up on Doxastic logic some time. All ‘knowledge’ is is integrated pattern consistency in our brains.
We can comprehend free will, but we can’t define it.
You can’t define it because it doesn’t exist. You’ve basically just admitted you literally do not know what you are talking about. Not that such an admission was necessary, since it is patent.
Humans are embodied spirits.
You may as well have said that humans are embodied Fnords. The word ‘spirit’ makes no sense in the magical sense which Christians use it, and ‘embodied’ is just an empty term you use to circumvent the obviously physical nature of awareness.
True science is that the bodies of human beings evolved from animals. Their souls were created by God. My Youtube video (The Truth About Evolution and Religion) has a quote from Stephen Jay Gould admitting this.
True science is not using magic as an explanation, because it’s not. You are almost certainly misquoting Gould, but in any case this is an appeal to authority and a lame authority at that. Gould has admitted that he lets his ideology steer what scientific views he will even consider. Congratulations, you’re following in his foot steps.
