Surely that's exactly what it's not saying for examples provide only
generalities. The key word in the quote is 'critical' (critical: 'involving
careful judgement or judicious evaluation' from my dictionary) ie the essence
is to look at the code and see WHY certain principles will IMPROVE the
The reason why most programmers do not produce good code is because, once they
have learned *A* method for accomplishing a task they simply repeat that method
ad infinitum without reflecting on whether there might be a better way.
Even if you whack them on the head with a better method they will at best just
take that new one and use it in future without thinking. People mostly just
don't like thinking (even smart ones sadly).
And of course there are other aspects to 'think' about to become a good
programmer. Understanding doesn't come easily - you have to keep looking and
thinking until the day you die (OK so I've been watching too many martial arts
The reason why *I* don't produce good code is entirely different, honest.
(Trying very hard not to turn this into a rant about the general uselessness
of people lest I give the impression of being old and embittered! :)
