Definition of Symmetry

Cambridge dictionary defines symmetry as ‘the quality of having  parts that match each other, especially in a way that is attractive, or similarity of shape or contents

As humans we love and enjoy symmetry.If there is slight deviation we feel it’s ugly.

But John Ruskin has a different view

“No human face is exactly the same in its lines on each side, no leaf perfect in its lobes, no branch in its symmetry. All admit irregularity as they imply change; and to banish imperfection is to destroy expression, to check exertion, to paralyze vitality. All things are literally better, lovelier, and more beloved for the imperfections which have been divinely appointed, that the law of human life may be Effort, and the law of human judgment, Mercy.”
