A garden is a complex of aesthetic and plastic intentions; and the plant is, to a landscape artist, not only a plant - rare, unusual, ordinary or doomed to disappearance - but it is also a color, a shape, a volume or an arabesque in itself.
Roberto Burle Marx

The more people explore the world, the more they realize in every country there's a different aesthetic. Beauty really is in the eye of the beholder.
Helena Christensen

Scientific understanding is often beautiful, a profoundly aesthetic experience which gives pleasure not unlike the reading of a great poem.
Paul Nurse
