When you believe in something passionately, it’s easy to get caught up in the principle of the thing, and forget the big picture. Conversely, it’s also easy to focus on the result and forget about the principles that get trampled in getting to the end.
Sometimes, the end justifies the means, and sometimes the means is the end. When you are arguing a position of principle in politics, the waters get even muddier.
Say I believe that global warming could be stopped in its tracks if we all wore pink underwear on thursdays. Say I also believe that wearing underwear with tassels helps me reduce my own “personal” greenhouse emissions.
What if the boss of underpants says, “I can help you with the pink underwear, but the tassels have got to go.”? In the big picture, the tassels aren’t important in the slightest, but if I cave on the tassels, then I place myself on the big slippery slope of being vulnerable to the boss of underpants forevermore. I open myself up to scrutiny that I am willing to do a deal with the boss, and I compromise my principles about tassels.
What I want, is pink underpants with tassels. What I can get without help, is khaki coloured y-fronts (which really don’t do anyone any favours). With help, I can get 90% of what I want, and I end up feeling like Lady Macbeth.
