"Master, " said Ling one day, "I think that all living nature is plain experimenting."
"Good, what makes you think so?"
"Everything alive is always trying, always trying things out. Plants, animals, children and puppies, grown-ups too."
"What brilliant jewel of a mind you have Ling! You see, ideation is ALWAYS problem solving, in other words, Reality is always a question for a Mind, a problem, is always "'whatsit?'. Fortunately there is one thing completely outside all experimentation in our Reality. All else is open to investigation. Mass, space, energy and electricity, movement, forces, light etc. can always be taken apart, be cooked, weighed, crushed, pressed, spun around, reflected, put under a microscope and so on except 'that what comes from outside the universe."
"And what is that Master?"
"But don't you know, it is TIME. Time cannot be induced or pushed, compressed, or taken a sample off. It is a regime enforced upon the whole universe from outside, everything is subject to it."
"But we can measure time master."
"Don't be silly Ling. You know as well as I do that what we call measuring is only giving a name to part of time, and then, it is just keeping it, as event, against another event and see how it tallies. We do not measure time, we simply use its effects. Time is a continual addition to the universe, therefore, the universe is an open system."
