gates of oblivion across the Sea of Lethe

Humanists, a recent news items says, are advertising their faith formally and publicly. The politcal implications should be obvious. Notice humanism largely exists as a counterpoint inside cultures putting it forth that they do believe in God. Sinking into oblivion on the Sea of Forgetfulness seems like the only hope humanistic atheists hold out for themselves. Also, seeing is believing, not scientific, but if they cannot prove something they disregard it in their world. I would think that if there were no future beyond their body's demise then they are released from all moral considerations. They are on a suicide mission to oblivion, like getting drunk on a mindless college night. They have no check or balance to rein in impulses. One can even lie if they wanted to, since there are no ten commandments to consider. They are their own moral compass. No wondering for them which man is worse off, the one who tells a lie, or the one who believes it.
