Do not let what you don't
know disturb what you do
know. You may ask questions about what you don't know, but never act on it
. Act only
on what you know.
Sounds obvious, eh? And yet there are so many people for whom this utterly correct thought means that you still act as if what you don't know is true
. That, of course is the opposite of the principle above, but I recognize that the precautionary principle
is an example of bad science and worse thinking that people engage in all the time.
The moral of the story is that there are always things to fear for those who wish to be afraid. For those who wish to do good in the world, fear is not your friend.
