I find this site very interesting, because the questions and answers span such a wide range of issues.
However, I often struggle to see how some of the matters discussed fit into the category of "Philosophy".
For example: How should the fair distribution of some goods depend on other-regarding preferences?
This seems to be a question that is far more relevant to political science, or economics than "Philosophy".
Yet this question: How do Buddhism, Hinduism, etc. address the 'problem of evil'? seems essentially a theological question and this one How should I understand the word corruption in this passage of the Bhagavad Gita? appears to be about linguistics and theology, with little connection to "Philosophy".
I understand that Philosophy is divided into sub-categories: Philosophy of Religion, Philosophy of Government, Philosophy of Economics, Philosophy of History, etc. But at what point does the discussion become a question of (for example) Philosophy of Religion, rather than Theology itself. Philosophy of Government, rather than political science itself, etc?
I could postulate that perhaps the way to delineate is to determine if the issue at hand is about the subject matter itself, for example Theology: "What does Canon Law say about how to refer to the various components of the Trinity" as opposed to reflection upon the subject matter: "What are the reasons that Canon Law has deemed these terms appropriate when referring to the components of the Trinity", which might be considered "Philosphy of Religion". Or History: "Who was King of France when the French Revolution took place", in contrast to "Why did some historians opine that the King of France was morally justified in resisting the Revolution"?
But I am groping - the lines of demarcation are not at all clear to me. I know that as late as the 17th and 18 centuries, what we call today a "scientist" was called a "philosopher": Someone engaged in deep and speculative thought and research.
Can someone send me to sources that might discuss this question, or provide some guidance on this matter?
