"Biology, meaning the science of all life, is a late notion"

This quote by Leon Kass suggests that the principle of biology, or the science of all life, is a fairly new idea. This implies that prior to the development of the field of biology, there was no unified understanding of life and its procedures. Instead, life was studied through a variety of different disciplines, such as medication, botany, zoology, and physiology. It was not up until the 19th century that the concept of biology became a distinct discipline, unifying the numerous branches of life science. This quote highlights the significance of biology in understanding the complexity of life, and how it has changed our understanding of the natural world.
