To judge a perfume is, above all else, a matter of taste. Taste evolves under the influence of the environment, but this fact must not prohibit judging the environment. Taste evolves chiefly with the acquisition of learning, with the knowledge of facts and of aesthetic accomplishments, which makes it possible to analyze them and to provoke instructive comparisons. It is thus that each of us can progress along the road of beauty and of art. To deny the usefulness of this training would be like refusing to admit that a symphony is better appreciated after one has studied music.
