In human terms, is not euthanasia a preferred and valid alternate to the artificial and selfish attitude of "life at all costs" now generally practiced?

If I hold a different world view than you, do you view me as wrong or ignorant?

Why is the Big Bang theory the most widely accepted theory of the creation of the universe?

Why do vegetarians, vegans, etc. propose a different set of rules for animals? After all, humans are animals too. Why can a lion kill and eat an antelope wheras a human cannot? Why does it matter that we do not 'need too'?

There are many different ways of acquiring knowledge, be it through experience, learning through books and teachers, and by practice. How can we differ what we have learnt from practice and experience from what we have been taught or "learnt"? This leads to thinking there are different types of knowledge like how to drive once we know how to, or to ride a bicycle once we've learnt to, or to apply a certain theory once we've been taught it. Upon which I ask, what is knowledge, and are there really different types of it?

Are there any contradictions of the Axiom of Choice (AOC) that are consistent with basic mathematical logic? Has anyone tried to develop a non-AOC theory?

Can something be infinite if there is a definitive number of it? Here's an example: I take a number, the largest I can think of, and never stop adding one to it. The number becomes infinite. Now if you take the number of human beings, and never stop adding to it, is the number of human beings infinite? In contrast, dinosaurs cannot be added to therefore they would not be infinite. Does this make sense?

Are animals capable of perceiving beauty (or, for that matter, ugliness)? Not just in other animals but in their surroundings as well. Bill Ray

If you have a dream and you do not remember it, and there is no one to reassure you that you actually had one (like if you get drunk and black out, but there are actual people to tell you that you did things), did you really have a dream?

Are you as Philosophers allowed to say that the rock on my desk is red? For we really don't know. We perceive it as red but what if our eyes are not showing us what is really there? For all we know, everything could be black and white.
