Quotes about immortality

Neither is the longing for immortality saved, but rather dissolved and submerged, by agnosticism, or the doctrine of the unknowable. ...The unknowable, if it is something more than the merely hitherto unknown, is but a purely negative concept, a concept of limitation. And upon this foundation no human feeling can be built up.

The truth is that we live out our lives putting off all that can be put off; perhaps we all know deep down that we are immortal and that, sooner or later, all men will do and know all things.

What the sorrowful Jew of Amsterdam called the essence of a thing, the effort that it makes to persist indefinitely in its own being, self-love, the longing for immortality, is it not perhaps the primal and fundamental condition of all reflective or human knowledge? And is it not therefore the true base, the real starting-point, of all philosophy, although the philosophers, perverted by intellectualism, do not recognize it?

Only the feeble resign themselves to final death and substitute some other desire for the longing for personal immortality. In the strong the zeal for perpetuity overrides the doubt of realizing it, and their superabundance of life overflows upon the other side of death.

Yes perhaps, as the Sage says, "nothing worthy of proving can be proven, nor yet disproven"; but can we restrain that instinct which urges man to wish to know, and above all to wish to know the things which conduce to life, to eternal life? Eternal life, not eternal knowledge as the Alexandrian gnostic said. For living is one thing and knowing is another; and... perhaps there is an opposition between the two that we may say that everything vital is anti-rational, not merely irrational, and that everything rational is anti-vital. And this is the basis of the tragic sense of life.

My undertaking is not difficult, essentially... I should only have to be immortal to carry it out.

Modern man may assert that he can dispense with them, and he may bolster his opinion by insisting that there is no scientific evidence of their truth. But since we are dealing with invisible and unknowable things (for God is beyond human understanding, and there is no mean of proving immortality), why should we bother with evidence?
