Who stated the twins objection ( that with close birth times , personal outcomes can be very different ) ?
He also argues that the interpretation of the moon 's conjunction with a planet as good when the moon is full , but bad when the moon is waning , is clearly wrong , as from the moon 's point of view , half of her surface is always in sunlight ; and from the planet 's point of view , waning should be better , as then the planet sees some light from the moon , but when the moon is full to us , it is dark , and therefore bad , on the side facing the planet .
