I am always asking 'why?'
What has led to an apparent difficulty?
So let us not talk about effects?
Let us talk instead about causes?
What principle is being applied to arrive at such a controversial conclusion?
Does that principle stand up to scrutiny?

The problem really is that it is difficult to change the thinking of a large group of people.
People adhere to outdated ideas and concepts with fervour.
They don't like change.
Rather like a large boat not being able to change course quickly.
So any change in thinking must be effected slowly.
Luckily, we are all amenable to reason, even if we don't react immediately.

No amount of wailing or waving magic wands will get a man to the moon.
Only dedicated effort, guided by strict reasoning, will accomplish that.
So it is truth and reason which make the changes we consider useful.
Witches stirring cauldrons have had their day.
