H. Rider Haggard said this quote

Yea, all things live forever, though at times they sleep and are forgotten.

~ H. Rider Haggard

Ah! how little knowledge does a man acquire in his life. He gathers it up like water, but like water it runs between his fingers, and yet, if his hands be but wet as though with dew, behold a generation of fools call out, 'See, he is a wise man!' Is it not so?

~ H. Rider Haggard

Yet man dies not whilst the world, at once his mother and his monument, remains. His name is lost, indeed, but the breath he breathed still stirs the pine-tops on the mountains, the sound of the words he spoke yet echoes on through space; the thoughts his brain gave birth to we have inherited to-day; his passions are our cause of life; the joys and sorrows that he knew are our familiar friends--the end from which he fled aghast will surely overtake us also!Truly the universe is full of ghosts, not sheeted churchyard spectres, but the inextinguishable elements of individual life, which having once been, can never die, though they blend and change, and change again for ever.

~ H. Rider Haggard

And now let us love and take that which is given us, and be happy; for in the grave there is no love and no warmth, nor any touching of the lips. Nothing perchance, or perchance but bitter memories of what might have been.

~ H. Rider Haggard
