“Presumption has many forms; and it is worth considering, whether a great and good Being would most disapprove the presumption which expected too much from His goodness, or the presumption which dared positively to disbelieve His promise.”

Preface to The Great Crusade (1940) by Gustav Regler

Conversation on Epictetus and Montaigne
Context: One, knowing the duties of man and being ignorant of his impotence, is lost in presumption, and that the other, knowing the impotence and being ignorant of the duty, falls into laxity; whence it seems that since the one leads to truth, the other to error, there would be formed from their alliance a perfect system of morals. But instead of this peace, nothing but war and a general ruin would result from their union; for the one establishing certainty, the other doubt, the one the greatness of man, the other his weakness, they would destroy the truths as well as the falsehoods of each other. So that they cannot subsist alone because of their defects, nor unite because of their opposition, and thus they break and destroy each other to give place to the truth of the Gospel. This it is that harmonizes the contrarieties by a wholly divine act, and uniting all that is true and expelling all that is false, thus makes of them a truly celestial wisdom in which those opposites accord that were incompatible in human doctrines.

Context: Loupgarou was come with all his giants, who, seeing Pantagruel in a manner alone, was carried away with temerity and presumption, for hopes that he had to kill the good man. Whereupon he said to his companions the giants, You wenchers of the low country, by Mahoom, if any of you undertake to fight against these men here, I will put you cruelly to death. It is my will, that you let me fight single. In the meantime you shall have good sport to look upon us.

Context: Christians, and some Jews, claim we're in the "end times," but they've been saying this off and on for more than two thousand years. According to Hindu cosmology, we're in the Kali Yuga, a dark period when the cow of history is balanced precariously on one leg, soon to topple. Then there are our new-age friends who believe that this December we're in for a global cage-rattling which, once the dust has settled, will usher in a great spiritual awakening.
Most of this apocalyptic noise appears to be just wishful thinking on the part of people who find life too messy and uncertain for comfort, let alone for serenity and mirth. The truth, from my perspective, is that the world, indeed, is ending – and is also being reborn. It's been doing that all day, every day, forever. Each time we exhale, the world ends; when we inhale, there can be, if we allow it, rebirth and spiritual renewal. It all transpires inside of us. In our consciousness, in our hearts. All the time.
Otherwise, ours is an old, old story with an interesting new wrinkle. Throughout most of our history, nothing – not flood, famine, plague, or new weapons – has endangered humanity one-tenth as much as the narcissistic ego, with its self-aggrandizing presumptions and its hell-hound spawn of fear and greed. The new wrinkle is that escalating advances in technology are nourishing the narcissistic ego the way chicken manure nourishes a rose bush, while exploding worldwide population is allowing its effects to multiply geometrically. Here's an idea: let's get over ourselves, buy a cherry pie, and go fall in love with life.
