Your Week Ahead: Jonathan and I once discussed why the olive branch became a universal symbol of peace. Olives have a challenging taste, he mused. Even when salted and pickled, you either love them or hate them. I suggested that perhaps we hope that peace, like the olive, can be easily preserved. Peace sometimes seems hard to attain, and even trickier to sustain. As many philosophers have observed, 'peace isn't just the absence of war.' They're right. But, as both Mercury and the Sun move towards conjunctions with Venus, it's a good place to start.
