Human beings are to be treated as ends and never as means. Respect for personality is the value that includes all other values. We do not live in a world of man made values unrelated to time and space. It makes all the difference in the world whether you believe this. If you do then you will know that in the universe around you there is a voice to which you can listen, a beauty to which you can aspire, and a perfection that awaits you.
Beliefs are important.
Everyone of you will live, everyone of you will give your life for what you believe in. Sometimes people believe in little or nothing at all. Then they give their lives for little or nothing at all. One life is all we have, and we live it as we believe in living it. Then it is gone.
