The sun is the global street lamp which goes out when it gets dark, just when we most need it. However we ( the lightseekers as opposed to the heatseekers) are able to turn the tables on nature, to turn night into day, to see in the dark , to hold up to Nature not the mirror but the two fingers. We are in control. We can fly to the moon; we can plummet to the bottom of the deepest ocean… The uses to which we have put our inventiveness is, to use the current vogue word, ‘awesome’. Three cheers for the human race.
