The Death of Socrates by Jacques-Louis David See www.pima.gov/publicdefender/socrates.htm
In this painting, Socrates (470–399 B.C.), un-coerced and unshackled, freely prepares to die by drinking poisonous hemlock. • The philosopher is condemned to die by the Athenian democracy for promoting skepticism and impiety; the Athenians were nervous about offending the gods (after losing to Sparta in the Peloponnesian War). Rather than flee the city, Socrates accepts his unjust punishment and sacrifices himself on abstract principle. • Nevertheless, Socrates shows nobility and self-control in the face of death. (Thoughts, Books and Philosophy; J H Bowden) See www.philosophypages.com
Socrates calmly sits upright with his finger extended in the air, exuding authority, responsibility, and intellect • Surrounding him are his students, most of them acting emotionally. The only students in control of themselves are Plato, seated resigned and unhappy at the end of the bed, and Crito, who has his hand on Socrates’ leg attempting to persuade him rationally not to die until the very end
Plato(428 – 347 BCE) Knowledge through reason, the intellect – not the senses. Knowledge of reality & how we perceive it: what is whiteness, roundness, treeness? (Metaphysics – meaning and reality) Theory of Forms / Ideas: world of the senses / change / illusion / appearance / imperfect vs the authentic world / ideas / unchangeable / spiritual / eternal The Republic – Allegory of the Cave What is spiritual truly exists; the soul – no changeability. Plato distrusted the senses Dualism - Body & soul in conflict; body imprisons soul Ethics – seek truth, goodness, beauty: focus on ‘upward’ journey to the spiritual realm Image courtesy of news.bbc.co.uk
Plato asks the young girl in Sophie’s World (by Jostein Gaarder) to think about the following 4 questions, thereby engaging in philosophy • Think over how a baker can bake 50 absolutely identical biscuits • Ask yourself why all horses are the same • Decide whether you think that [the human person] has an immortal soul • Say whether men and women are equally sensible
Aristotle (384 – 322 BCE) Interested in scientific proof & principle of cause & effect Whiteness, treeness, justice etc exist – called these ‘forms’ Form and matter: recognises the essence of something & its physical manifestation: what makes me unique + the physical characteristics I exhibit. Both need each other. Form = what makes something what it is: whiteness, treeness, it is unchanging; matter = individual, particular, concrete, it changes. Knowledge begins with the senses. 2 ways of knowing: through the senses first + then through the intellect. We must use our senses as well as our intellect. Seasons: senses tell us there is change. Intellect tells us why. Within change there is stability and a foundation for scientific thought / principles Image courtesy of space.about.com
