The range of foolish and evil things of which we human beings are capable of never ceases to astonish. We destroy our bodies and sometimes our brains with controlled substances, even though we know better. We make stupid choices that we know in advance will lead to trouble. We devastate our marriages and friendships by repeating the same mistakes again and again. How often we've heard it said, quite correctly, 'she's married the same man again.'
And that's just the stupid part. There's also the downright evil side of us, the lying, cheating, stealing and killing, the willingness to wage war for no good reason, the willingness to tolerate an unjust society, the willingness to turn our backs on the poor and the suffering. All in all, between stupidity and downright evil, this human nature of ours seems a fairly nasty piece of work.
It's not wrong, is it? How much of yourself do you see in that quote? What could you do to make the changes, to be a different person? Very often it is the minor changes we make in our behaviour and our attitude that make the biggest differences.
