In everything, no matter what it may be, uniformity is undesirable. Leaving something incomplete makes it interesting and gives one the feeling that is room for growth.

Found this quote off Google Books, but I Googled it as it was a quote Marcus du Sautoy used in his lecture on TED.COM about Symmetry.

I found this quote rather interesting because from a philosophical point of view, I agree wholeheartedly with the quote. Diversity is what gives us our strength. Diversity and its variability lets us overcome obstacles. And from this diversity, we can create even more variety to overcome even more variability in our world.

Yet, is uniformity not nature’s perfection? We are biologically programed to be drawn to symmetrical faces. The most stable structures on this planet are symmetrical.
