Well, yes and no. What you've got here is a tangle, just the sort of tangle that actually does lead to serious philosophical problems. You see, what you've got in the first place isn't exactly a syllogism. So, it's neither a valid nor an invalid syllogism. It looks a lot like the following syllogistic form (which is invalid): "All P are M. All S are M. Therefore, All S are P." You can see that this invalid by plugging in the following terms. "All Pigs are Mammals. All Siberian Huskies are Mammals. Therefore, all Siberian Huskies are Pigs." While the two premises are true, the conclusion is clearly false--and that doesn't happen in valid arguments. This invalid form doesn't have a specific name, really, but it does commit the fallacy of "undistributed middle." I think one reason you may have lost your way here is because you use equal signs in your presentation. If you intend to use the equal sign as short hand for the verb "to be" ("are") in the same what as I have used "to be" ("are") in my example,...

I guess I think that the most important thing would be for philosophy to be taught more widely. I think it a scandal, for example, that logic isn't required in every school--primary, middle, high school, and university--across the country. How is it that we've come to require geometry but not basic logic? Training in ethics, political philosophy, and the history of philosophy ought to be widespread. Philosophers ought also to be sought out to serve as advisers for political leaders, and philosophical training ought to be more highly regarded as a credential for hiring people into positions of leadership. You may know that already insurance companies and hospitals commonly employ medical ethicists in making policy decisions. We need more of that. Philosophers ought to be more deeply engaged in public discourses. More newspaper columns, tv commentators, and popular writers ought to be philosophers.

Gosh, wouldn't it be great if everyone were a metaphysician? Unfortunately, using ideas that metaphysicians explore no more makes one a metaphysician than using using religious concepts makes one a theologian. There's no simple definition of "metaphysics," but as a serviceable start one might say that metaphysics is that branch of philosophy that investigates the most fundamental and the most general features of reality or what we think about reality. So, for example, while a historian might ask, "What were the causes of the Crimean War?" A metaphysician might ask, "What is history, what is time and history, what are historical causes, and what are human agents such that they can engage in war?" While a biochemist might ask, "What are the compounds that cause a specific reaction in the intestines?" A metaphysician might ask, "What is 'Being' generally, and what is causation generally?" While someone might ask whether or not she should return a wallet she's found on the ground, a metaphysician might ask...

I think I see what you mean. But if I do, then the phrase "arbitrary for humans" is not exactly the way to pose your question. Humans aren't really making the choice in your scenario. So, the choice is neither arbitrary nor non-arbitrary for them. I think you might rather mean something like: Would God's arbitrarily commanding any conduct provide sufficient grounds for humans to regard that conduct as good? My sense is that the qualities of a lot of religious faith lead people to answer in the affirmative. In particular, for the faithful it's likely to be almost inconceivable to defy God's command on grounds that what's commanded seems immoral from a merely human point of view. The story of Abraham and Isaac exemplifies just this sort tendency in faith. The problem is that it seems to many at least as intolerable to accept that stealing, rape, mass murder, etc. could ever be acceptable. For example, many will find it intolerable to honor a command to torture, molest, mutilate, and kill innocent children-...

Yeah, I think that's right. The theistic hypothesis is not testable through the procedures of natural science. That in itself has led many, myself included, to a kind of agnosticism about theism. That's also one of the reasons why neither creationism nor much of what is described as intelligent design are scientific. Do note, however, that testability may not be the only basis for rejecting (or accepting) theism. Some reject theism because they find theistic language itself intolerably confused and senseless. Others point to the political and moral problems associated with theisms (the violence, the intolerance, the blunting of norms of reason and critical thinking). (I frequently find that line of reasoning attractive.) Some object to the way theism fails to produce agreement and generates divisions and sects. (Often compelling to me, too.) Along similar lines, others have concluded that it's simply undesirable to commit to beliefs that are excessively complex or, alternatively not as simple as...

Given the way many in the wealthy parts of the world live, this is a compelling question. I think, however, that as posed the answer must be "no." For one thing, the best paying jobs may sometimes contribute more bads than goods to the world. For example, in some circumstances criminal activity or highly polluting industry may offer the best paying job. Also, it is not morally obligatory to live off as little as one can manage, giving away the rest to charity. People have obligations to themselves as well as to others, and one must balance what one owes to others against what one owes oneself. Finally, it's important to understand that some acts are morally admirable without being morally obligatory; and from where I sit extraordinary self-sacrifice for the sake of charity to others counts as just such an act. Having said that, it remains true, I think, as a matter of judgment, that many people in wealthier parts of the world live in ways that have tipped the balance excessively in the direction of...

No and yes. Historically, the idea of toleration developed along side streams of philosophical scrutiny of religious belief that suggested, rightly I think, that there's just not very good reason for zealous commitment to religious beliefs. So, while a zealot may, as you describe it, be exceedingly confident or dogmatic in his or her belief, there's no sound justification for doing so. In this sense, strains of modern skepticism have tempered religious belief in the form of what early modern thinkers called "enthusiasm." But, on the other hand, there are many ways of holding a belief "strongly." There are, one might say, ways of holding religious beliefs strongly that are consistent with tolerance and ways of holding beliefs strongly that are inconsistent. Tolerance itself commonly suggests that contrary views are considered wrong and even, perhaps, obnoxious. So, analogously, we speak of a body's capacity to tolerate a toxin or to tolerate the cold, etc. So, just as we might speak of a person who...

This is a wonderfully knotty question that has occupied philosophers at least since Zeno of Elea in the 5th century BCE. One way of interpreting Zeno on this is to say that the problem shows that space is illusory. David Hume later, like the atomists ('atom' meaning uncuttable) seems to have thought that there must be a point at which the cutting stops, at least so far as the world of experience goes. I might say that Zeno is right that certain ways of conceiving space are flawed, including the way the problem as you pose it conceives of space--that is, as continuous all the way down, becoming just a finer and finer Cartesian grid if you will, always subject to the same sorts of properties or ways of conceiving things (like length, height, depth, etc.). It seems, however, that once we reach the sub-atomic realm these ways of conceiving things just don't hold, so that it becomes impossible to apply mathematical divisions of space. Space seems dependent on, you might say, the ability of energy to...

While in general truth-telling is morally preferable to lying, I suppose it might depend upon what precise reason one has for preferring not to answer or precisely how wrong or in what way wrong the question was. But as a general matter, no, I don't think it reasonable to hold that it would always be wrong to lie in circumstances of the sort you describe.

The texts of intimate relationships are generally too complicated to make judgments about using simple moral principles. But as a weakly stated general rule, I'd say that it's not wrong to marry or simply remain in a marriage out of a sense of duty. In fact, I would say that a sense of duty is a desirable element of a good foundation for marriage. It is, however, wrong to marry or remain married for the sake of duty but do so deceptively--that is, it is wrong to marry or stay married only or principally for sake of duty when your partner in marriage believes otherwise.
