And it isn't today, which coincidentally is when we are talking.
Science and philosophy education and practice has essentially no overlap. They're separate fields pursued using different approaches by different people. The fact that scientists have opinions on epistemological questions doesn't make science a philosophy any more than any other field.
You are mistaken. Science and Philosophy are tied together at the hip, as this discussion of Quantum Mechanics in this thread clearly illustrates. Besides, I had to do philosophy when I was studying and it has helped me immensely in my medical career, especially navigating the murky worlds of Neurology, Psychiatry and Evidence-Based practice.
Whether you like it or not, Science is merely a subdivision of Philosophy and this idea that Science somehow uses different methods than philosophy is merely a damning indictment of our Education system. I don't know about the US, but where I am from, most Scientific careers and Medical fields are obligated to do a little formal philosophy.
For someone who used a train on the tracks analogy for brain function you're suddenly getting very literal when it suits you.
You clearly did not understand my analogy at all. I used it to illustrate the fallacious idea that a pathway is the same as the function that requires it. It is of course not a perfect analogy, nor meant to be.
Just to explain a bit more: Pain can be demonstated. I can explain to you exactly how the impulse travels, what receptors are activated, what neurotransmitters are employed etc. It is only in the last aspect of conscious perception that we can no longer follow what is going on fully. Thought and Reason cannot be so described nor shown how nerve functioning directly correlates to it in the same manner.
But as I said previously, no one is denying that neuronal function is not directly related to thought and Reason, just that it is not necessarily solely responsible for it.
Does any of this obfuscation have anything to do with the fact that correctly interpreting sense data to avoid falling off cliffs vs. not provides a differential survival rate which would result in evolutionary change?
The one obfuscating here would be you, as you have altered your premise a bit now. But yes, it would result in evolutionary change, but will that change result in a realistic view of reality or the rise of Reason?
You are once again treading into an epistemological quagmire by using the term 'correctly'. This is once more begging the question.
But if you read what was said earlier in the thread, we already discussed this at length. We are trying to ascertain if Reason and a true estimation of reality can arise from Evolution. As I explained earlier, our estimation might not be accurate and likely wouldn't be for all individuals, thus not allowing us to know if ours is.
Also there is a difference between thinking 'if I fall of the cliff, I will die, which is bad, so I must avoid it' and simple avoidance strategy. Jellyfish and tubeworms also do not approach their predators or dangerous situations. Is complex reasoning occuring here? Instinct and simple response pathways can explain this well enough without any reality testing being necessary or coming into play. You withdraw your hand from a hot surface before you become consciously aware of it, for instance.
