Full Idea
I already know what death is like - it will be the same after me as it was before me. ..Only an utter idiot would think a lamp was worse off when it was put out than before it was lit. ..What does it matter whether you cease to be or never begin?
Gist of Idea
We know death, which is like before birth; ceasing to be and never beginning are the same
