William Harvey Quotes
And so I conclude that blood lives and is nourished of itself and in no way depends on any other part of the body as being prior to it or more excellent... So that from this we may perceive the causes not only of life in general... but also of longer or shorter life, of sleeping and waking, of skill, of strength and so forth.
Harvey, William. Anatomical Exercises on the Generation of Animals. Translated by Robert Willis, Sydenham Society, 1847, p. 376.
The law is far behind science in many areas, but one dramatic one is the notion of life itself. For the criminal law and for benefits entitlement, when life begins and when it ends are traditionally important. Yet is a very complex question in many cases. Abortion is another controversial area. Under ancient Jewish Law, a fetus is considered a living person when the crown of the head can be viewed from the mother’s vagina. Modern science has demonstrated that depending on how you define life, the fetus itself is alive during the pregnancy. But if one goes further with modern science, the sperm and egg cells are alive before conception. So are millions of other cells in the human body which we kill routinely—some intentionally as when we take an antibiotic to terminate “undesirable” bacteria. Many orthodox Hindus who will not kill living animals will kill living cells such as when they eat yogurt. Scientists have in recent times resisted trying to define the term “living” not only because of its complexity, but because almost any definition would soon be obsoleted by new knowledge which is accumulating so rapidly. Science simplifies and clarified many phenomena, but also makes others much more complex.
William Harvey was an English physician who made influential contributions in anatomy and physiology. He was the first known physician to describe completely, and in detail, the systemic circulation and properties of blood being pumped to the brain and the rest of the body by the heart, though earlier writers, such as Realdo Colombo, Michael Servetus, and Jacques Dubois, had provided precursors of the theory.
