Existence is Victory over Non-Existence

Well, the title is taken from the the words of St Thomas Aquinas the doctor of the catholic Church. He is a great theologian and a philosopher who gave the philosophical reasons to prove how the life/existence is precious on the face of the earth. Indeed it is very true and in agree to his valuable words. The very fact that we are existing is the fact that we have defeated the nonexistence by which there is the victory of life over non-life. Besides this Thomas Aquinas tells us that human mind or the intellect is ever great on this face of the earth if compared to any existing being.
