The Japanese philosophy of wabi-sabi accepts the transience and embraces the beauty that is "imperfect, impermanent, and incomplete". The wabi-sabi aesthetic recognizes that time will pass and materials will wear - and designs for it.
The simplicity of wabi-sabi is best described as the state of grace arrived at by a sober, modest, heartfelt intelligence…Usually this implies a limited palette of materials. It also means keeping conspicuous features to a minimum. But it doesn’t mean removing the invisible connective tissue that somehow binds the elements into a meaningful whole. It also doesn’t mean in any way diminishing something’s “interestingness”, the quality that compels us to look at that something over, and over, and over again.In addition to the source of the above passage, Wabi-Sabi: for Artists, Designers, Poets & Philosophers, I should look at About Time and Eternally Yours: Design in Time, a collection of writings on product endurance and durability.
