From the Hindu perspective, each soul is divine. All religions are branches of one big tree. It doesn't matter what you call Him just as long as you call. Just as cinematic images appear to be real but are only combinations of light and shade, so is the universal variety a delusion. The planetary spheres, with their countless forms of life, are naught but figures in a cosmic motion picture. One's values are profoundly changed when he is finally convinced that creation is only a vast motion picture and that not in, but beyond, lies his own ultimate reality.
George Harrison
If I use the name 'Hesperus' to refer to a certain planetary body when seen in a certain celestial position in the evening, it will not therefore be a necessary truth that Hesperus is ever seen in the evening. That depends on various contingent facts about people being there to see and things like that. So even if I should say to myself that I will use 'Hesperus' to name the heavenly body I see in the evening in yonder position of the sky, it will not be necessary that Hesperus was ever seen in the evening. But it may be a priori in that this is how I have determined the referent.
Saul Kripke
Those to whom we look for solutions trundle on as if nothing has changed. As if the accumulating evidence has no purchase on their minds. Decades of institutional failure ensures that only "unrealistic” proposals – the repurposing of economic life, with immediate effect – now have a realistic chance of stopping the planetary death spiral. And only those who stand outside the failed institutions can lead this effort. Two tasks need to be performed simultaneously: throwing ourselves at the possibility of averting collapse, as Extinction Rebellion is doing, slight though this possibility may appear; and preparing ourselves for the likely failure of these efforts, terrifying as this prospect is. Both tasks require a complete revision of our relationship with the living planet.
George Monbiot
The inhibitions placed on the irresponsible use of technology are weak, often half-hearted, and almost always, worldwide, subordinated to short-term national or corporate interest. We are now able, intentionally or inadvertently, to alter the global environment. Just how far along we are in working the various prophesied planetary catastrophes is still a matter of scholarly debate. But that we are able to do so is now beyond question.
Carl Sagan
This was the evening of the last day of Gordon Way's life ... The weather forecast hadn't mentioned that, of course, that wasn't the job of the weather forecast, but then his horoscope had been pretty misleading as well. It had mentioned an unusual amount of planetary activity in his sign and had urged him to differentiate between what he thought he wanted and what he actually needed, and suggested that he should tackle emotional or work problems with determination and complete honesty, but had inexplicably failed to mention that he would be dead before the day was out.
Douglas Adams
As a boy Kepler had been captured by a vision of cosmic splendour, a harmony of the worlds which he sought so tirelessly all his life. Harmony in this world eluded him. His three laws of planetary motion represent, we now know, a real harmony of the worlds, but to Kepler they were only incidental to his quest for a cosmic system based on the Perfect Solids, a system which, it turns out, existed only in his mind. Yet from his work, we have found that scientific laws pervade all of nature, that the same rules apply on Earth as in the skies, that we can find a resonance, a harmony, between the way we think and the way the world works.
When he found that his long cherished beliefs did not agree with the most precise observations, he accepted the uncomfortable facts, he preferred the hard truth to his dearest illusions. That is the heart of science.
Carl Sagan
A law explains a set of observations; a theory explains a set of laws. The quintessential illustration of this jump in level is the way in which Newton's theory of mechanics explained Kepler's law of planetary motion. Basically, a law applies to observed phenomena in one domain (e.g., planetary bodies and their movements), while a theory is intended to unify phenomena in many domains. Thus, Newton's theory of mechanics explained not only Kepler's laws, but also Galileo's findings about the motion of balls rolling down an inclined plane, as well as the pattern of oceanic tides. Unlike laws, theories often postulate unobservable objects as part of their explanatory mechanism. So, for instance, Freud's theory of mind relies upon the unobservable ego, superego, and id, and in modern physics we have theories of elementary particles that postulate various types of quarks, all of which have yet to be observed.
