Though Nature is like unto herself in the organizing force or in her principles which are infinite, she is not so in her finite effects. Thus you will never find in Nature two objects identically alike.

Context

“Your Numeration, applying to things finite and not to the Infinite, is therefore true in relation to the details which you are able to perceive, and false in relation to the Whole, which you are unable to perceive. Though Nature is like unto herself in the organizing force or in her principles which are infinite, she is not so in her finite effects. Thus you will never find in Nature two objects identically alike. In the Natural Order two and two never make four; to do so, four exactly similar units must be had, and you know how impossible it is to find two leaves alike on the same tree, or two trees alike of the same species.” source
