Dugas goes further, and asserts that the ideals of modesty develop with human development, and forever take on new and finer forms. "There is," he declares, "a very close relationship between naturalness, or sincerity, and modesty, for in love, naturalness is the ideal attained, and modesty is only the fear of coming short of that ideal. Naturalness is the sign and the test of perfect love. It is the sign of it, for, when love can show itself natural and true, one may conclude that it is purified of its unavowable imperfections or defects, of its alloy of wretched and petty passions, its grossness, its chimerical notions, that it has become strong and healthy and vigorous. It is the ordeal of it, for to show itself natural, to be always true, without shrinking, it must have all the lovable qualities, and have them without seeking, as a second nature. What we call 'natural,' is indeed really acquired; it is the gift of a physical and moral evolution which it is precisely the object of modesty to keep. Modesty is the feeling of the true, that is to say, of the healthy, in love; it long exists as a vision, not yet attained; vague, yet sufficiently clear for all that deviates from it to be repelled as offensive and painful. At first, a remote and seemingly inaccessible ideal, as it comes nearer it grows human and individual, and emerges from the region of dream, ceasing not to be loved as ideal, even when it is possessed as real.
