Letters 119.15

Among other things, Nature has bestowed upon us this special boon: she relieves sheer necessity of squeamishness. The superfluous things admit of choice; we say: “That is not suitable”; “this is not well recommended”; “that hurts my eyesight.” The Builder of the universe, who laid down for us the laws of life, provided that we should exist in well-being, but not in luxury. Everything conducive to our well-being is prepared and ready to our hands; but what luxury requires can never be got together except with wretchedness and anxiety.
