  1. Bryan Magee _ Karl Popper

    Men presumably always have looked at flowers and been moved by their beauty and their smell: but only since the last century has it been possible to take a flower in your hand and know that you have between your fingers a complex association of organic compounds containing carbon, hydrogen, oxygen, nitrogen, phosphorus, and a great many other elements, in a complex structure of cells, all of which have evolved from a single cell; and to know something of the internal structure of these cells, and the processes by which they evolved, and the genetic process by which this flower was begun, and will produce other flowers; to know in detail how the light from it is reflected to your eye; and to know the details of those workings of your eye, and your nose, and your neurophysiological system, which enable you to see and smell and touch the flower. These inexhaustible and almost incredible realities which are all around us and within us are recent discoveries which are still being explored, while similar new discoveries continue to be made; and we have before us an endless vista of such new possibilities stretching into the future, all of it beyond man's wildest dreams until almost the age we ourselves are living in. Popper's ever present and vivid sense of this, and of the fact that every discovering opens up new problems for us, informs his theoretical methodology. He knows that our ignorance grows with our knowledge, and that we shall therefore always have more questions than answers.

  2. Neil deGrasse Tyson

    We have one collective hope: the Earth And yet, uncounted people remain hopeless, famine and calamity abound Sufferers hurl themselves into the arms of war; people kill and get killed in the name of someone else's concept of GodDo we admit that our thoughts & behaviors spring from a belief that the world revolves around us? Each fabricated conflict, self-murdering bomb, vanished airplane, every fictionalized dictator, biased or partisan, and wayward son, are part of the curtains of society's racial, ethnic, religious, national, and cultural conflicts, and you find the human ego turning the knobs and pulling the levers When I track the orbits of asteroids, comets, and planets, each one a pirouetting dancer in a cosmic ballet, choreographed by the forces of gravity, I see beyond the plight of humans I see a universe ever-expanding, with its galaxies embedded within the ever-stretching four-dimensional fabric of space and time However big our world is, our hearts, our minds, our outsize atlases, the universe is even bigger There are more stars in the universe than grains of sand on the world's beaches, more stars in the universe than seconds of time that have passed since Earth formed, more stars than words & sounds ever uttered by all humans who have ever livedThe day we cease the exploration of the cosmos is the day we threaten the continuing of our species In that bleak world, arms-bearing, resource-hungry people & nations would be prone to act on their low-contracted prejudices, and would have seen the last gasp of human enlightenmen
