In a designed economy there would be no trees, or certainly no very tall trees: no forests, no canopy. Trees are a waste. Trees are extravagant. Tree trunks are standing monuments to futile competition - futile if we think in terms of a planed economy. But the natural economy is not planned. Individual plants compete with other plants, of the same and other species, and the result is that they grow taller and taller, far taller than any planner would recommend. ↗
My entry into the environmental arena was through the issue that so dramatically - and destructively - demonstrates the link between science and social action: nuclear weapons. ↗
Something cascaded lightly through me—a gentling, a suffused glow. If love could be morphed into a physical element, this would be it. It was strength and yet it was vulnerability. It was all-encompassing and yet it was freedom. It was a wall of protection. It was wings of trust and faith. It was Gabriel Ross Sullivan, answering the questions I couldn’t ask. Not that everything would be okay, but that everything in his power would be done, and we’d face whatever outcomes there were together. ↗
They were a remarkable company, each one of them a unique person, yet characterized to some extent by his particular national type. And all were distinctively “scientists” of the period. Formerly this would have implied a rather uncritical leaning towards materialism, and an affectation of cynicism; but by now it was fashionable to profess an equally uncritical belief that all natural phenomena were manifestations of the cosmic mind. In both periods, when a man passed beyond the sphere of his own serious scientific work he chose his beliefs irresponsibly, according to his taste, much as he chose his recreation or his food. ↗
But it so happens that everything on this planet is, ultimately, irrational; there is not, and cannot be, any reason for the causal connexion of things, if only because our use of the word "reason" already implies the idea of causal connexion. But, even if we avoid this fundamental difficulty, Hume said that causal connexion was not merely unprovable, but unthinkable; and, in shallower waters still, one cannot assign a true reason why water should flow down hill, or sugar taste sweet in the mouth. Attempts to explain these simple matters always progress into a learned lucidity, and on further analysis retire to a remote stronghold where every thing is irrational and unthinkable. If you cut off a man's head, he dies. Why? Because it kills him. That is really the whole answer. Learned excursions into anatomy and physiology only beg the question; it does not explain why the heart is necessary to life to say that it is a vital organ. Yet that is exactly what is done, the trick that is played on every inquiring mind. Why cannot I see in the dark? Because light is necessary to sight. No confusion of that issue by talk of rods and cones, and optical centres, and foci, and lenses, and vibrations is very different to Edwin Arthwait's treatment of the long-suffering English language. Knowledge is really confined to experience. The laws of Nature are, as Kant said, the laws of our minds, and, as Huxley said, the generalization of observed facts. It is, therefore, no argument against ceremonial magic to say that it is "absurd" to try to raise a thunderstorm by beating a drum; it is not even fair to say that you have tried the experiment, found it would not work, and so perceived it to be "impossible." You might as well claim that, as you had taken paint and canvas, and not produced a Rembrandt, it was evident that the pictures attributed to his painting were really produced in quite a different way. You do not see why the skull of a parricide should help you to raise a dead man, as you do not see why the mercury in a thermometer should rise and fall, though you elaborately pretend that you do; and you could not raise a dead man by the aid of the skull of a parricide, just as you could not play the violin like Kreisler; though in the latter case you might modestly add that you thought you could learn. This is not the special pleading of a professed magician; it boils down to the advice not to judge subjects of which you are perfectly ignorant, and is to be found, stated in clearer and lovelier language, in the Essays of Thomas Henry Huxley. ↗
[Think] of an experience from your childhood. Something you remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren't you? How else would you remember it? But here is the bombshell: you weren't there. Not a single atom that is in your body today was there when that event took place . . . Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made. If that doesn't make the hair stand up on the back of your neck, read it again until it does, because it is important. ↗
