Science, which was teleological in pre-modern times and knowing the end was considered one of its most important pillars, in an epistemological evolution, not only the necessity of teleological state of science was denied, but it has been viewed also as a hindrance against the progress of science and the flourishing of human experience. The attitude led to omitting teleology from the field. Three issues can be raised about modern science: 1- The fundamental difference between pre-modern science and that of postmodern and that modern science as the latter is not teleological contrary to the former. 2- The destructive and corrupting results of modern science. 3- The need of natural sciences to religion and revelation for perceiving the ends of beings. This article, using an analytical-descriptive method, is responsible for examining the first issue and analyzes and examines the process of evolution of science with regard to the omission mentioned.

The ideas of man`s ​​dominating nature and of the endless nature began with the writings of Roger Bacon in the thirteenth century and was completed by the theories of Galileo, Francis Bacon, Descartes and Newton in the sixteenth and seventeenth centuries
