Karl Marx was once asked to give his favorite epigram. He thought for a second before offering up, De omnibus dubitandum est*.
Which translated would be, ‘Everything, must be doubted’
As epigrams go, I think, its an amazing choice.
*coincidentally… or maybe not, this also the title of a book by Søren Kierkegaard (more or less the father of existentialism)
I often like to imagine that Marx had good intentions when he laid out his philosophy and given time to see how his ideas started playing out he likely would have changed his mind. (well I hope he would have)
In any event, words to live by, spoken by an unlikely source.
