Was mathematics invented or discovered?

What would it mean to say that mathematics was invented and how would this be different from saying mathematics was discovered? Is this even a serious philosophical question or just a meaningless/tautological linguistic ambiguity?

Why don't fair coin tosses "add up"? Or... is "gambler's fallacy" really valid?

I have always been perplexed by a seeming paradox in probability that I'm sure has some simple, well-known explanation. We say that a "fair coin" or whatever has "no memory." At each toss the odds are once again reset at 50:50. Hence the "gambler's…

Am I morally obligated to pursue a career in medicine?

I am a high school student who has no formal training in philosophy, so I apologize if this question seems naïve. However, it is one that I am currently facing in a life decision, and I would like a philosopher's input on the matter. I am nearing…

How does one know one is not dreaming?

How does one know one is not dreaming? How could one logically demonstrate to a skeptic that one is "really" there, awake and not just dreaming about the entire situation/world around him? What I'm asking is: which if any philosophers have addressed…

What would it take in a book to convince a rational person that it had been written by or directly inspired by a god?

Many of the world's religions are based on a book or text that adherents claim to have been written by or directly inspired by a god, perhaps omniscient, omnipotent and omnibenevolent. My question is whether there is anything, in principle, that…

Is Kurt Gödel's Incompleteness Theorem a "cheap trick"?

I found a throw-away critique of Kurt Gödel's Incompleteness Theorem in an essay about Deconstruction: The basic enterprise of contemporary literary criticism is actually quite simple. It is based on the observation that with a sufficient amount…

Could 'cogito ergo sum' possibly be false?

I've heard it postulated by some people that "we can't truly know anything". While that does seem to apply to the vast majority of things, I can't see how 'cogito ergo sum' can possibly be false. No matter what I am, no matter in what way I'm…

Can you prove anything in philosophy?

I don't understand philosophy very well, and so I am wondering whether you can "prove" anything in philosophy. It always seems you can go a layer down, and find another question, almost endlessly until you get to the question of "why/how/are we…

Is it immoral to download music illegally?

I should first point out that the title is more to capture a common occurrence of the broader idea I want to address in this question. It is also somewhat incorrect in that—at least in the US—I'm not sure it's actually illegal to download music…

How can an uneducated but rational person differentiate between science and religion?

I recently found myself unable to respond to the statement "But the big bang theory is just another creation myth!" during a science vs. religion argument. I found it very difficult to explain the difference between the big bang theory and creation…

Why is there something instead of nothing?

A simple but fundamental question. The "something" means the whole Universe (known and unknown), it could be represented as the reality version of the set of all sets, which is itself debated. It includes all the Multiverses and such. A better…

Logical fallacy: X is bad, Y is worse, thus X is not bad

I have heard this type of argument too many times: You are criticising X using well researched facts and arguments. Your interlocutor, states that Y is much worse with equally well researched facts and arguments. X and Y are linked in a general…

Does human life have innate value over that of other animals?

Does human life have innate value over that of other animals? If so, why? And is it wrong to murder another human, but morally permissible to hunt or fish?

Why is faith seen as a sign of weakness, instead of an unexplored land/opportunity?

Hope this is the right place to put this question! I am a person of faith (more specific, a Christian) and most of the time people consider me somehow inferior for my belief. I am not antisocial, not sick, nor crazy, but rather rational (even if…
