“The fear of death is instinctive because in so many past generations we have feared it. But how did we come to know what death is so that we should fear it? The answer is that we do not know what death is and that this is why we fear it. ii If a man know not life which he hath seen how shall he know death which he hath not seen? iii If a man has sent his teeth and his hair and perhaps two or three limbs to the grave before him, the presumption should be that, as he knows nothing further of these when they have once left him, so will he know nothing of the rest of him when it too is dead.” source
