I combat those only who, knowing nothing of the future, prophesy an eternity of pain- those who sow the seeds of fear in the hearts of men- those only who poison all the springs of life, and seat a skeleton at every feast

The notion that faith in Christ is to be rewarded by an eternity of bliss, while a dependence upon reason, observation, and experience merits everlasting pain, is too absurd for refutation, and can be relieved only by that unhappy mixture of insanity and ignorance called 'faith.'

In the presence of eternity, the mountains are as transient as the clouds.

The Old Testament describes the hell of the past, and the New the hell of the future

The present is the necessary product of all the past, the necessary cause of all the future

We can conceive of eternity because we cannot conceive of a cessation of time. We can conceive of infinite space because we cannot conceive of so much matter that our imagination will not stand upon the farthest star and see infinite space beyond.
