I think this is all coming together. We each see the value of what has come before in Philosophy/Science and how it has contributed to where we are today. You take the view that I have things wrong-way-round as to the schism, and I the opposite view. Let's address it.
I think we need to look very carefully at your last paragraph above. One of Scientific Philosophy's (Science
) main premises is that we must acknowledge and address that in trying to answer any question, it is imperfect and fallible human beings that are asking and trying to answer these questions.
I can understand how you might say a particular individual may display "a desire to avoid questioning numerous values, motivations, foundations and assumption" about their particular disciple, but this is the nature of human beings. Surely you agree that this is a trait exhibited in all aspects of life, including Philosophy as practiced today. I have yet to see you acknowledge any issue or concern with the way Philosophy is practiced.
So, if we can agree that this avoidance trait is found in individuals in all endeavors, the next question to ask is, "Is this trait recognized by the discipline in question, and does this discipline take active steps to mitigate this issue?"
You want to imply that Scientific Philosophy is designed or practiced, as a discipline, to actively avoid your referenced list of things avoided. This is simply not true. The whole process of scientific philosophy is about building from what we know, and as we make progress and add to that base of knowledge, new data or information must prompt a reevaluation of old and new information together to ensure our understanding and conclusion remain intact. This was touched on in your second Einstein quote. It is this constant process of reevaluation that allows Scientific Philosophy to make meaningful progress in answering general and fundamental questions.
Let's look at Philosophy in this same light. Is there anything in Philosophy, in a branch of Philosophy that structurally wishes to avoid questioning numerous values, motivations, foundations and assumptions on which their Philosophy rests, or overstates their ability to validate their belief?
I'm not going to spoon feed you. I hope you will carefully consider and be able to come up with examples.
Holy Cow! And case-in-point right back at ya. That Scientific Philosophy, or at least some practitioners, get bogged down in reductionism is not a fundamental flaw of scientific philosophy, it is a flaw of investigators. Scientific Philosophy is self-correcting, as is apparently the case in that we continue to strive to get a handle on complexity. This is the process. This is how it works. Breaking things down and looking at how constituent parts works. Putting things back together and observing the complex system with this new-found knowledge, works. This is how it is done.
Your last paragraph does not make sense to me. Granted it is probably down to ignorance on my part. What is it you mean by 'complex systems' and why is it in single quotes?
To say that science has become increasingly interdisciplinary as a result of philosophical changes I will only agree with if by philosophical you mean the attitudes of the scientific disciplines. If you mean to imply that Philosophy as a discipline influenced science to become interdisciplinary, you are going to have to demonstrate that. I am incredulous.
Biology majors, for example, are required to take Physics, Mathematics, and extensive Chemistry, along with the interdisciplinary field of Biochemistry. Becoming interdisciplinary was necessitated by the work and the level of advancement in the field of Biology, a self-evident requirement.
What I would suggest is that scientists took philosophy with them when the split occurred, that science still kept philosophy. The schism occurred because a portion of the Philosophical community would not adopt the new best practices of Philosophy. This resulted in those using best practices falling under the label Science, and those adhering to traditional outdated practices maintaining the label Philosophy. This is the schism. Two branches with the same goal, one branch using improved guiding principles and standards that incorporate mitigating the effects of the flawed observer, and the branch that continued to do things in an outmoded way, highly vulnerable to human fallibility.
I am by no means saying that nothing of value has come from Philosophy since the schism. What I am saying, however, is that there are aspects of current philosophical practice that are sheltered under the label Philosophy that require evaluation under modern best practices.
And here you throw in the word 'natural'. And this is a demonstration that it is Philosophy, or rather, those who wish to keep Philosophy separate from Science, do so in an effort to shield all of Philosophy from scientific best practices. Branches of Philosophy founded on nothing more than imagination.
