eye" (p. 25); "Neurology is a modern medical discipline .... Hippocratic writings... revealed only a rudimentary understanding of anatomy and physiology" (p. 208). McGrew may well be right, recently published biographical and conceptual dictionaries on the history of science and philosophy are all, however distinguished their editors and contributors, "Whiggish". Perhaps popularization, which i...

For millennia, people have regarded life as being synonymous with breathing. Life begins and ends with breathing. The Bible states that God " breathed into [Adam's] nostrils the breath of life, " and then later used part of Adam's ventilatory apparatus — a rib — to give life to Eve. In the fourth and fifth centuries BC, writings attributed to Hippocrates suggested that the primary purpose of br...

The techniques of natural duality theory are applied to certain finitely generated varieties of Heyting algebras to obtain optimal dualities for these varieties, and thereby to address algebraic questions about them. In particular, a complete characterisation is given of the endodualisable finite subdirectly irreducible Heyting algebras. The procedures involved rely heavily on Priestley duality...

A piggyback duality and a translation process between this one and a Priestley duality for each subvariety of involutive Stone algebras and regular o-De Morgan algebras is presented. As a consequence we describe free algebras and the prime spectrum of each subvariety.
