Human inner nature allows people to seek after values such as truth, beauty, and goodness. In addition to the desire to realize beauty through his or her own deeds, a person wishes to gain joy from seeing beauty in nature and works of art, and through reading books. The construction of the human eye, which allows one to see color and to see the fine print in a book, contributes to this ability to see beauty. Color adds a rich dimension beyond simply seeing things as shades of gray. Visual acuity, to be able to discern fine detail, adds a dimension of sight beyond simply see blurs of movement. While color may be important for bees and birds to find the showy flowers with nectar, and visual acuity may be important for a bird of prey to find that small mouse to eat while flying high in the sky, for humans the color and visual acuity means an enhanced ability to experience the beauty of creation and create works of art.
The mammalian eye is extraordinarily complex. For some, this represents an irreducible complexity, and they question how such an organ can come about gradually, built on intermediaries. However, Charles Darwin himself proposed a solution to this problem, and it is generally held that the eye gradually evolved from simple sense organs, that could only detect light, to the complex color vision of birds and mammals. However, the fact that the eye could have developed from precursors does not mean that it came about via the chance phenomena involved in natural selection. Externally, it would seem to have evolved from higher to lower. However, religious views postulate that this pattern of evolution came about through the design of a creator. Unification Thought further holds that the end result of a person existed in the mind of the creator, such that the creation of all things in the universe were based on the final image. This gives the point of view common to Western Theologies that a person is a “microcosm” of creation.
