No straight lines are to be found in the natural world……..Leonard Shlain has pointed out that the only apparently straight line in the natural world is that of the horizon, but of course that too turns out to be a section of a curve……..Straight lines are prevalent wherever the left hemisphere predominates. Iain McGilchrist. The Master and his Emissary
By contrast the shape that is suggested by the processing of the right hemisphere is that of the circle, and its movement is characteristically ‘in the round’, the phrase we use to describe something that is seen as a whole, and in depth. Iain McGilchrist. The Master and his Emissary
So, if the left hemisphere prefers straight lines, and straight lines don’t really occur in nature, and the right hemisphere prefers to see things in the round, then why not go out this weekend, and see how many round shapes you can see? Strengthen seeing with your right hemisphere!

Hmm -I wonder how this fits with my aversion to straight lines in my gardens – always? Bending pathways, asymmetrical hedging, daffodils in clusters not along borders, herbs in groups and vegetables in blocks.
The human structure internally and externally is never in straight lines. Visualisation with hands on treatment is fascinating with long curves, waves, spirals. spheres and spiderlike webs through fascia.
I love this group of pictures, especially the lily pad and the round window.
