I have a simple, 4 word philosophy. It encompasses all that is relevant in the great religions, humanism, atheism and reason. It applies to all situations, from work to love, and everywhere in between. If it had been in force universally, there would be no wars, no crime, no over-the-top rapacious capitalism, no PC-brigade. Freedom for all. And what are those four words, I hear you cry?
Don't be a dick.
In any situation where there is conflict,discord, disharmony or harm, there is always at least one dick. There may be many, but you should always ask "Am I being a dick?". If you think you might be - STOP, and make things right.
