The aircraft falls out of the sky or rams the earth full tilt and kills the people. It has to be tended like a new born babe. Our dinner table ought to be variable in size and height, removable altogether, impervious to scratches, self-cleaning, and having no legs.

Indeed they admit themselves that it is the Egyptians, the Chaldeans and the Phoenicians (for I will not now include ourselves Jews among those) that have preserved the memory of the most ancient and lasting tradition. , Josephus, (Quoted in Toulmin and Goodfield,The Discovery of Time, The University of Chicago Press, 1965, p. 25.),I cannot but greatly wonder,36,“,My advice is to get married: if you find a good wife youll be happy; if not youll become a philosopher.”,Deep Philosophy,From Socrates,“My advice is to get married:,37,Thank You,Thank You,38,“,The only useful knowledge is that which betters us.”,- Socrates,“The only useful knowledge is,39,Plato vs. Aristotle,Particular was less real,Substance is transitory,Form is static,Fear of change,Founded academy,Mystic,Belittler of natural science,Mathhighest form of thinking,Universe was less real,Substance needs matter,True nature evolves,Change inevitable to progress,Founded Lyceum,Logician,Observer of natural science,Separated math and science,Plato vs. AristotleParticular,40,Platonic vs. Pre-Socratic,World is an ordered cosmos,Pervasive intelligence,Order transcends physical manifestation,Complete knowledge,Full understanding satisfies the mind and soul,Knowledge acquired through reason,Truth is transitory,Natural phenomena are impersonal and physical,Theory measured against empirical knowledge,No thought is final,Platonic vs. Pre-SocraticWorld,41,“,Concerning the gods, I have no means of knowing whether they exist or not, nor of what form they are; for there are many obstacles to such knowledge, including the obscurity of the subject and the shortness of human life.”, Protagoras (a Sophist),“Concerning the gods, I have,42,Socrates,Taught a barbarian the Pythagorean Theorem,Knowledge is intuitive and is merely revealed by learning,“Know thyself.”,Socrates,+,=,SocratesTaught a barbarian the,43,For Plato knowing is an act of making the observable world intelligible by showing how it is related to an eternal order of intelligible truths.“, Palmer, Donald,Does the Center Hold?, Mountain View, CA: Mayfield Publishing Company, 1991, p. 58.,For Plato knowing is an ac,44,The essence (or form, as he Aristotle called it, borrowing Platos term.) is the things whatness, and its materiality is its thisness. That is, an oak trees whatness, its essence or form, is the combination of characteristics that make it an oak tree rather than, say, a pussy cat; and its thisness is its individuality what distinguishes,this,oak tree from all other oak trees., Palmer, Donald,Does the Center Hold?, Mountain View, CA: Mayfield Publishing Company, 1991, p. 162-163,.,The essence (or form, as h,45,“,Aristotles universe was composed of a plurality of real beings that fell into an orderly hierarchy of perfection. Prime matter and substantial form were the principles of every physical body. The simplest bodies occurring in nature were the four elements, earth, air, fire and water. These combined to produce the various types of inanimate objects. Living things were more complex bodies which were united by a higher type of substantial form, called soul. Aristotle distinguished three types of souls, vegetative, sensitive, and rational, corresponding to the degrees of perfection found in plants, animals, and human beings.”, Langford in,Galileo, Science and the Church,“Aristotles universe was comp,46,Socrates,Socratic Method,Posed questions and then questioned the answers,Searched for the,ultimate nature,of qualities,What is Duty?,What is Truth?,What is Evil?,SocratesSocratic Method,47,Happiness is the consequence not of physical or external circumstances, of wealth or power or reputation, but of living a life that is good for the soul. Yet to live a genuinely good life, one must know what is the nature and essence of the good., Richard Tarnas in,The Passion of the Western Mind,Socrates taught:,Happiness is the consequence,48,The works of Homer had embodied the aristocratic values that Plato wished to support, but Homer had offered no defense of those values except an appeal to the emotions through his poetic discourse. If Plato was to defend values rationally, he had to replace the power of poetry (as manifested in Greek myth and drama) with that of philosophy, the spokeswoman for reason.,Palmer, Donald,Does the Center Hold?, Mountain View, CA: Mayfield Publishing Company, 1991, p. 60.,The works of Homer had embod,49,From the Pythagorean perspective, the fundamentals of existence are the archetypal Forms or Ideas, which constitute the intangible substrate of all that is tangible. The true structure of the world is revealed not by the senses, but by the intellect, which in its highest state has direct access to the Ideas governing reality. All knowledge presupposes the abstraction or imaginary metaphor for the concrete world, is here considered to be the very basis of reality, that which determines its order and renders it knowable. To this end, Pythagoras and later Plato declared direct experience of the transcendent Ideas to be the philosophers primary goal and ultimate destination.,Tarnas,The Passion of the Western Mind, p 12.,From the Pythagorean perspect,50,For Plato the Creation of the cosmos was the process by which the eternal mathematical principles were given material embodiment, imposing an order on the formless raw materials of the world, and setting them working according to ideal specifications. When a mathematician worked out the geometrical relations manifested in the motions of the planets, or the properties of material substances, he was likewise revealing the Craftsmans rational design.“,Toulmin, Stephen and June Goodfield,The Discovery of Time, The University of Chicago Press, 1965, p.42-43.,For Plato the Creation of,51,Aristotle believed that the world we are born into,is,the real world and is not just a shadow of a more ultimate world. He brought Platos philosophy down to earth by claiming that the Forms must be imbedded in matter. He believed that the distinction between Form and matter was only an,intellectual,distinction, a distinction that could be drawn in theory but not in reality.,Palmer, Donald,Does the Center Hold?, Mountain View, CA: Mayfield Publishing Company, 1991, p. 448.,Aristotle believed that the,52,“,Good people do not need laws to tell them to act responsibly, while bad people will find a way around the laws.”,Plato,“Good people do not need laws,53,
