The universe is what it is, not what I choose that it should be. If it is indifferent to human desires, as it seems to be; if human life is a passing episode, hardly noticeable in the vastness of cosmic processes; if there is no superhuman and supernatural purpose, and no hope of ultimate salvation, it is far better to understand and acknowledge this truth than to endeavor, in futile self-assertion, to order the universe to be what we may find comfortable.

The universe is neither hostile nor friendly; it neither favors our ideals nor refutes them. Our individual life is brief, and perhaps the whole life of humankind will be brief if measured on an astronomical scale. But that is no reason for not living it as seems best to us. The things that seem to us good are none the less good for not being eternal, and we should not ask of the universe an external approval of our own ethical standards.

The freethinker’s universe may seem bleak and cold to those who have been accustomed to the comfortable indoor warmth of the various religious cosmologies. But to those who have grown accustomed to it, it has its own sublimity, and confers its own joys. In learning to think freely we have hopefully learnt to thrust fear out of our thoughts, and this lesson, once learnt, brings a kind of peace which is impossible to the slave of hesitant and uncertain credulity.
