Do I have an obligation to be healthy in virtue of the fact that my health problems contribute to higher health care premiums for other people?

Is the statement, "the only rule is that there are no rules" the same in meaning as "there are no rules"? Why would a person ever necessarily use the first statement?

What is the the truth value, if they have one, of propositions whose subject do not exist? "The current king of France is bald" is the famous example. Is that true or false, or neither? I have a hard time understanding how the current king of France can be neither bald nor not bald, even though I have no trouble understanding that there is no current king of France.

Why do we do anything if nothing lasts forever? Every action we make is but a blip on the finite timeline of the universe, ending with the heat death. All our actions fade into insignificance as they become the past. Similarly, on a smaller scale, why do we do things if life is finite too? What difference would it make to the individual who is unable to witness the effect of his actions?

Is pragmatic truth inherently less valid than other forms of truth? If a Hindu believes in the truth that Vishnu exists and a Muslim does not, how could they both be right? I don't know how to word this, but are the correspondence and epistemic theories of truth the most "true?"

Could having children be considered forcing life upon somebody who never asked for it?

I'm going to ask a somewhat bizarre question concerning casuality, probability, and the nature of belief so bear with me thanks! Suppose a craps player goes to two casinos in Macau, the first one architecturally built according to feng shui principles and a second one not according to feng shui principles. Feng shui is an ancient Chinese system of geomancy that modern psychologists tend to discredit. This craps player personally believes in feng shui himself but only to a moderate extent. He frequents both casinos equally and bets exactly the same way every time but he usually wins at the first casino and usually loses at the second casino. 1) Does this prove that feng shui is "real," at least for him? 2) Pragmatically, even if feng shui isn't "real" or cannot be proven to be real, isn't it advisable for him to stop going to the second casino? 3) Can psychology really influence probability involving human decisions?

More people are familiar with the ideas of Camus and Sartre, two examples of continental philosophers who wrote of the need of philosophy to be applied to the human condition, than are aware who Quine and Wittgenstein were. Does it bother analytic philosophers that most people consider analytic philosophy to have zero relevance in their lives yet regard many continental philosophers as public intellectuals?

Most currencies in the world today are issued by governments. Does this mean that money only has value because governments assign it value? By this definition, are commodities more valuable than money since value is assigned by individuals instead of governments?

Is it immoral to play poker (a game that inherently involves bluffing) full time to make a living even if it is more profitable for someone than a traditional job? Even if we consider it a sport akin to tennis or golf, it does not create economic value in the sense that's it's usually not being broadcast and there are no spectators or advertising. Players do not contribute to the tax base and social insurance; money is just being passed around from person to person.
