- Crabs are decapod crustaceans of the infraorder Brachyura, which typically have a very short projecting “tail” (abdomen), usually hidden entirely under the thorax (brachyura means “short tail” in Greek). They live in all the world’s oceans, in freshwater, and on land, are generally covered with a thick exoskeleton, and have a single pair of pincers. They first appeared during the Jurassic Period.
- Francis Bacon (plato.standford.edu)
Francis Bacon (1561–1626) was one of the leading figures in natural philosophy and in the field of scientific methodology in the period of transition from the Renaissance to the early modern era. As a lawyer, member of Parliament, and Queen’s Counsel, Bacon wrote on questions of law, state and religion, as well as on contemporary politics; but he also published texts in which he speculated on possible conceptions of society, and he pondered questions of ethics (Essays) even in his works on natural philosophy (The Advancement of Learning).
