text: A cucumber is bitter.- Throw it away.- There are briars in the road.- Turn aside from them.- This is enough. Do not add, And why were such things made in the world? For thou wilt be ridiculed by a man who is acquainted with nature, as thou wouldst be ridiculed by a carpenter and shoemaker if thou didst find fault because thou seest in their workshop shavings and cuttings from the things which they make. And yet they have places into which they can throw these shavings and cuttings, and the universal nature has no external space; but the wondrous part of her art is that though she has circumscribed herself, everything within her which appears to decay and to grow old and to be useless she changes into herself, and again makes other new things from these very same, so that she requires neither substance from without nor wants a place into which she may cast that which decays. She is content then with her own space, and her own matter and her own art.
