It is unreasonable to ask that we prove everything that we accept as true. In fact, any kind of proof or demonstration ultimately depends on principles that are accepted as true without proof. These principles are called axioms.
I know of at least three kinds of axioms:
The United Nations as well as the constitution of many countries take it as an axiomatic principle that the right to life is an inalienable human right. It is in the constitution without proof because it is taken as axiomatic (or a morally evident principle). Therefore, Nate13 is quite correct in insisting that “If you can first give me a proof why you have an inalienable right to life, then I can show you why an unborn human being has an inalienable right to life.” He is right in refusing to prove what is already morally evident. It is simply not possible, and it is not needed.
Likewise, the fact that a zygote, an embryo or a fetus is human, is physically evident already to one who knows from experience that it is the natural offspring of two human parents. If you try to argue that a human embryo is human to one who rejects this axiomatic principle, then your opponent will win the day. You cannot prove anything to him who rejects the first principle on which your argument hangs. With him you can only make appeal to his common sense, and pray that he might open his mind and heart to grace.

I know of at least three kinds of axioms:
- Self-evident principles - or propositions whose truth becomes evident as soon as the terms of the proposition are understood. Example: “In any finite collection the whole is larger than a part.” These kinds of principles are mostly found in mathematics and metaphysics (or first philosophy).
- Physical principles or laws derived from direct observation or experience. Example: “Every body tends to keep its state of motion unless acted upon by some external force.” Newton did not need to prove this law of motion because it is evident from experience. This type of principles is mostly found in the experimental and empiriological sciences of nature (physics, chemistry, biology, etc.).
- Moral principles or laws that proceed from our consciousness as human beings. Example: “Murder (or the killing of an innocent human being) is wrong.” This principle is universally accepted as true, not because it is found to be one of the 10 commandments, but because its denial goes against our conscience as human beings. Morally evident principles are the axioms found in moral philosophy (individual and social ethics).
