Even Humphrey Johns has to take a moment to assimilate this.

Johns
You what?
McBroom
'Put the law in people's minds and write it on their hearts.'
McBroom (chuckles again, looking exceedingly pleased with himself)
There, I've stumped you! I bet even you can't find anything to complain about in one of God's ideas! Ha ha ha!
Johns (takes a deep breath)
Nevertheless, I'll do my best. Skipping over the issue of how exactly you're going to write the law on people's hearts…
McBroom
Felt-tip pen.
Johns
…yes, skipping over that bit: are you mad? If we're reliant on people's hearts won't they do whatever they like?
McBroom
Ah, maybe, some of them, maybe. But I have a great deal of faith in the human heart, Humphrey.

'Land of hope and glory' begins to play softly in the background.

McBroom
The human heart is not a piece of paper or an edict. It's not a policeman trying to control an unwilling mob. The human heart is not a boy skipping school, or a thief trying to escape punishment. Its feelings can't be carved in simple words on tablets of stone and its power isn't dependent on governments or personalities, because you listen to your heart! Listen to your heart when he's calling for you, listen to your heart, there's nothing else you can do! I don't know where you're going and I don't know why, but listen to your heart before you tell him goodbye!

The music stops.

Johns
I'm going to interrupt you again now that I've managed to turn off that music, and be even more sarcastic for a moment.
McBroom
Oh, fine.
Johns
Isn't the real danger here that, having written the law on people's hearts, people will make things as strict as they would have been with your stone tablets?
McBroom
I don't follow you.
Johns
People will start to pass judgements on everything, they'll make decisions about what the law really means and find ways of making everything a whole lot harder for the people around them! Instead of using common sense and justice to interpret the law written on their hearts they will take what they know and make it ten times harsher!
McBroom (clears his throat)
Well – er – the government, obviously, can take no responsibility for… er…
Johns
Come on Mr McBroom, not losing faith in your grand idea are you?
McBroom
Of course not, ah… everything has been fully, er, considered and the point of the fact of the point remains that, ah…
Johns
Admit it, you're losing control of your party and playing into the hands of the opposition!
McBroom
I… er… the thing is… (suddenly snaps out of it, crossly) No, hang on a minute! I'm not taking this from you any more! My idea will give people amazing freedom; why on earth would anyone with the law written on their heart make it stricter than it's intended to be? They'd be missing the point completely and I refuse to believe anyone could be quite so stupid!
Johns (interrupting during the above from McBroom)
Well, that's all we have time for Prime Minister. I have to say I can't see this idea even gaining any support. It's now time for Thought for the Day , with the Rabbi Jeremiah Hilkiahson, chaplain to the Land of Benjamin.
Jeremiah
Well good morning Humphrey, good morning Prime Minister and good morning everyone. As my old mother used to say 'It's no use telling kids. Write it down and they will lose the paper. Lads will never learn until the law is written on their hearts…' I wonder if Mr McBroom had a Jewish mother, and, whether she made chicken soup like mine did?
