If the probability of death is 100%, and the probability of being alive tomorrow is uncertain, does that mean the probability of dying tomorrow is greater than the probability of being alive? If so, why am I so convinced that...

Hey there! My question is: is randomness an illusion or can everything theoretically be predicted? Let me use the coin toss analogy. At first, a coin toss appears totally random, but as we look deeper, we find...

My question is in part about language and in part about the nature of causality. I have noticed that some persons use the phrases "at random" or "by chance" in ways that make no sense to me. For instance, someone might...

Suppose I agree with theists that "God exists" is a necessary proposition, and so is either a tautology or contradiction. That seems to indicate that the probability of "God exists" is either 1 or 0. Suppose also that I don't...

Question posted on June 25, 2009; 1 response
In the probability thread, multiple philosophers mention examples of zero-probability events that aren't necessarily "impossible" (like flipping an infinite number of heads in a row). Arriving at a probability of zero in these instances relies on saying that 1/infinity =...

In support of the argument to design, people often remark that the order seen in nature is "improbable" and so requires a special explanation--i.e., a designer. But if order is seen throughout nature, in what sense is it improbable?...

Derren Brown recently had a show in which he flipped ten heads in a row. He just flipped coins all day and waited for it to happen eventually. If I flip a fair coin, I should believe there's a 50%...

Does it make sense to talk of "probability" with regard to existential claims? Consider the following propositions: (1) Rolling snake eyes is improbable. (2) The existence of Big Foot is improbable. Though I can't quite finger the distinction, it seems to me that...
