Question: Who was the father of the person "Principles of Philosophy" was dedicated to?
Context: Principles of Philosophy (Latin: "Principia philosophiae" ) is a book by René Descartes.  In essence it is a synthesis of the "Discourse on Method" and "Meditations on First Philosophy" It was written in Latin, published in 1644 and dedicated to Elisabeth of Bohemia, with whom Descartes had a long-standing friendship.  A French version ("Les Principes de la Philosophie") followed in 1647.  It set forth the principles of nature—the Laws of Physics—as Descartes viewed them.  Most notably, it set forth the principle that in the absence of external forces, an object's motion will be uniform and in a straight line.  Newton borrowed this principle from Descartes and included it in his own "Principia"; to this day, it is still generally referred to as Newton's First Law of Motion.  The book was primarily intended to replace the Aristotelian curriculum then used in French and British Universities.  The work provides a systematic statement of his metaphysics and natural philosophy, and represents the first truly comprehensive, mechanistic account of the universe. Maximilian de Gaynesford (born 1968) is an English philosopher and the author of "The Rift in the Lute: Attuning Poetry and Philosophy" (Oxford, 2017).  He was educated at Ampleforth College and Balliol College, Oxford (1986–9; First in Modern History), after which he spent several years studying Theology, before turning to Philosophy in 1993.  Before receiving his doctorate, he was elected Fellow and Tutor in Philosophy at Lincoln College, Oxford (1997).  He was subsequently Humboldt Research Fellow at the Freie Universität Berlin (2003) and a tenured professor at The College of William and Mary in Virginia (2002–2006) before becoming Professor of Philosophy (2008) and Head of Department (2016) at the University of Reading.  He is the author of over forty articles and four books: "The Rift in the Lute: Attuning Poetry and Philosophy" (Oxford, 2017), "I: The Meaning of the First Person Term" (Oxford, 2006), "Hilary Putnam" (Routledge, 2006), and "John McDowell" (Polity, 2004).  In 2011, he edited a collection of articles on the Philosophy of Action, "Agents And Their Actions" (Blackwell), which includes recent work by John McDowell and Joseph Raz.  He often gives papers on attuning poetry and philosophy for general audiences, as here .  He spoke at the Harvard Conference in celebration of Hilary Putnam, here .  He has a daughter, Elisabeth (born 2009). Pragmaticism is a term used by Charles Sanders Peirce for his pragmatic philosophy starting in 1905, in order to distance himself and it from pragmatism, the original name, which had been used in a manner he did not approve of in the "literary journals".  Peirce in 1905 announced his coinage "pragmaticism", saying that it was "ugly enough to be safe from kidnappers" ("Collected Papers" (CP) 5.414).  Today, outside of philosophy, "pragmatism" is often taken to refer to a compromise of aims or principles, even a ruthless search for mercenary advantage.  Peirce gave other or more specific reasons for the distinction in a surviving draft letter that year and in later writings.  Peirce's pragmatism, that is, pragmaticism, differed in Peirce's view from other pragmatisms by its commitments to the spirit of strict logic, the immutability of truth, the reality of infinity, and the difference between (1) actively willing to control thought, to doubt, to weigh reasons, and (2) willing not to exert the will, willing to believe.  In his view his pragmatism is, strictly speaking, not itself a whole philosophy, but instead a general method for the clarification of ideas.  He first publicly formulated his pragmatism as an aspect of scientific logic along with principles of statistics and modes of inference in his "Illustrations of the Logic of Science" series of articles in 1877-8. Elisabeth of the Palatinate (26 December 1618 – 11 February 1680), also known as Elisabeth of Bohemia, Princess Elisabeth of the Palatinate, or Princess-Abbess of Herford Abbey, was the eldest daughter of Frederick V, Elector Palatine (who was briefly King of Bohemia), and Elizabeth Stuart.  She was born in Heidelberg, Germany, spending the first nine years of her life there.  When she was nine, she went to live in Leyden, with her brother and was raised in a nursery palace to complete her studies.  After finishing her studies, she was deemed ready to live in The Hague with her mother. The Three Principles of the People, also translated as Three People's Principles, San-min Doctrine, or Tridemism is a political philosophy developed by Sun Yat-sen as part of a philosophy to make China a free, prosperous, and powerful nation.  The three principles are often translated into and summarized as nationalism, democracy, and the livelihood of the people.  He believed that the economic livelihood of the people depended on adopting the teachings of the American economist Henry George, writing that "The teachings of your single-taxer, Henry George, will be the basis of our program of reform." In computer programming, the term SOLID is a mnemonic acronym for five design principles intended to make software designs more understandable, flexible and maintainable.  The principles are a subset of many principles promoted by Robert C. Martin, .  Though they apply to any object-oriented design, the SOLID principles can also form a core philosophy for methodologies such as agile development or Adaptive Software Development.  The SOLID acronym was introduced by Michael Feathers. Groundwork of the Metaphysics of Morals (German: "Grundlegung zur Metaphysik der Sitten" ; 1785; also known as the "Foundations of the Metaphysics of Morals", "Grounding of the Metaphysics of Morals" and the "Grounding for the Metaphysics of Morals") is the first of Immanuel Kant's mature works on moral philosophy and remains one of the most influential in the field.  Kant conceives his investigation as a work of foundational ethics—one that clears the ground for future research by explaining the core concepts and principles of moral theory and showing that they are normative for rational agents.  Kant aspires to nothing less than this: to lay bare the fundamental principle of morality and show that it applies to us.  In the text, Kant provides a groundbreaking argument that the rightness of an action is determined by the character of the principle that a person chooses to act upon.  Kant thus stands in stark contrast to the moral sense theories and teleological moral theories that dominated moral philosophy at the time he was writing.  Central to the work is the role of what Kant refers to as the categorical imperative, the concept that one must act only according to that precept which he or she would will to become a universal law. In Canadian and New Zealand law, fundamental justice is the fairness underlying the administration of justice and its operation.  The principles of fundamental justice are specific legal principles that command "significant societal consensus" as "fundamental to the way in which the legal system ought fairly to operate", per "R v Malmo-Levine".  These principles may stipulate basic procedural rights afforded to anyone facing an adjudicative process or procedure that affects fundamental rights and freedoms, and certain substantive standards related to the rule of law that regulate the actions of the state (e.g., the rule against unclear or vague laws).  The degree of protection dictated by these standards and procedural rights vary in accordance with the precise context, involving a contextual analysis of the affected person's interests.  In other words, the more a person's rights or interests are adversely affected, the more procedural or substantive protections must be afforded to that person in order to respect the principles of fundamental justice.  A legislative or administrative framework that respects the principles of fundamental justice, as such, must be fundamentally fair to the person affected, but does not necessarily have to strike the "right balance" between individual and societal interests in general. A first principle is a basic, foundational, self-evident proposition or assumption that cannot be deduced from any other proposition or assumption.  In philosophy, first principles are taught by Aristotelians and a nuanced version of first principles are referred to as postulates by Kantians.  In mathematics, first principles are referred to as axioms and postulates.  In physics and other sciences, theoretical work is said to be from first principles, or "ab initio", if it starts directly at the level of established science and does not make assumptions such as empirical model and parameter fitting. Principia philosophiae cartesianae (PPC; "The Principles of Cartesian Philosophy") or Renati Descartes principia philosophiae, more geometrico demonstrata ("The Principles of René Descartes' Philosophy, Demonstrated in Geometrical Order") is a philosophical work of Baruch Spinoza published in Amsterdam in 1663.  In the preface to this work, Ludovic Meyer explains that it is a reconstruction of René Descartes' "Principles of Philosophy "in the Euclidean or "geometric" fashion".  "In the appendix, a series of non-geometric prose passages entitled "Metaphysical Thoughts" ["Cogitata Metaphisica"], Spinoza explicates Descartes' views on traditional metaphysical topics (including essence, existence, idea, potential, necessity, contingency, duration, and time) while furtively interpolating some of his own.
