We will never know in this life what happens after it. Our philosophy must therefore be grounded in the present. If I behave rightly today and I have a positive influence upon other coexistent souls, then I should behave rightly. If I behave rightly today and it carries forward to some incorporeal venue, then I should behave rightly. If I behave rightly and it impacts only my own soul and no others, present of future, then as much as ever I must behave rightly.
