The Oracle of Delphi were a priestess supposedly delivered messages from Apollo to those who sought advice; the messages were usually obscure or ambiguous.

People came all over Greece and beyond to have their questions about the future answered by the Pythia, the priestess of Apollo. Her answer could determine the course of everything from when a farmer planted his seedlings, to when an empire declared war.

In spiritual terminology, piety is a virtue. While different people may understand its meaning differently, it is generally used to refer to religious devotion or to spirituality, or often a combination of both. A common element in most conception of piety is humility.

The Phaedo begins when Echecrates asks Phaedo to tell him about Socrates’ death, and Phaedo warmly welcomes the chance to remember his friend Socrates in the final hours of his life. He says that it was an astonishing experience because although he was witnessing the death of a dear friend, he had no pity because of the way in which Socrates bravely and happily faced it, unafraid of the unknown.

In the days prior to Socrates’ death, Phaedo and other friends frequently visited Socrates in jail. Each time they discuss something new and interesting, including Socrates’ thoughts on why it is wrong to kill one’s self. Socrates thinks that it shows disrespect to the gods when one chooses to commit suicide because men are possessions of the gods and the gods are right to be angry if one of their possessions kills himself.

Cebes thinks that what Socrates has said doesn’t make sense because the wise should always want to be with better people than him so he can learn from them, as philosophers want to do. If one dies, one will not be with wiser people anymore and so the wise should resent death while the foolish should rejoice at it Socrates then tries to defend his argument by showing Cebes and Simmias that if death is the separation of the soul from the body, the philosopher by being a philosopher seeks to have himself separated as much as possible from his body because the body inhibits the mind. And therefore, the philosopher practices death everyday in his life. So the philosopher, as an example of “the wise” would not resent death as Cebes originally thought.

The men then take up discussion on what exactly death is, and Socrates tells a lot of qualities of the soul in the opinion of Plato. He says that the soul is capable of reasoning and thought, and that those capacities alone can grasp relevant objects, so he believes that no thought at all can be reached through the senses of the body which means that he thought knowledge could be attained completely independent of experience.

The Phaedo ends with Socrates saying that the soul is immortal; it requires our care in life by being good so that we may fare well in death. Obviously philosophers were considered by Plato to have the best souls because they spent their lives in search of knowledge and therefore they can make better choices and have a better chance of choosing a good life, all because of the knowledge that they acquired and the way in which they lived their lives.

Finally, Socrates drinks the hemlock and his friends become quite upset. Phaedo says that he felt ashamed for crying when Socrates was so dignified, and then the great philosopher and man took his last breath of air before dying. Those who knew him held him best held him in such high regard at the very end of his life, and at perhaps the most poignant time in his life-his death.

In his poem, Parmenides describes that reality is one, change is impossible and existence is timeless. Parmenides claimed that truth cannot be recognized by the sensory perception. And can only be understood with pure reason. In his poem he explains the world of appearances, and that it is false and deceitful. These thoughts greatly influenced Plato.

The common understanding of Parmenides’ work is that he argued that every-day perception of reality is mistaken. And in real the world is ‘One Being’. It is undeniable that Parmenides inspired Plato, and through him the rest of the western philosophy. He is often referred to as the grandfather of philosophy. In ‘The Sophist” Plato refers to the work of “our father Parmenides” as something to be taken very seriously and treated with respect.

Socrates says in Theaetetus that Parmenides, along with other philosophers denied that everything is change and motion. Parmenides argued that “movement was impossible because it requires moving into “the void”, and Parmenides identified “the void” with nothing, and therefore (by definition) it does not exist.” [?]

Zeno accompanied his teacher on a trip to Athens in 449 B.C. There he met a young Socrates and made enough of an impression to be included as a character in one of Plato’s books Parmenides. On his return to Elea he became active in politics and eventually was arrested for taking part in a plot against the city’s tyrant Nearchus. For his role in the conspiracy, he was tortured to death.

The four famous paradoxes of Zeno are the Dichotomy, Achilles, The Arrow and The Stadium. The most famous of the paradoxes, Achilles and the tortoise, is attributed to Parmenides himself. It is meant to show that motion is impossible. In a race where a tortoise is given a head start on Achilles, Achilles can never overtake the tortoise. He must first reach the place from which the tortoise started. By that time the tortoise will have got some way ahead. Achilles must then make up that and again the tortoise will be ahead. Zeno’s four most discussed paradoxes have been resolved in terms of differential calculus by Bertrand Russell, who claimed that Zeno should not be dismissed as a mere inventor of ingenious puzzles. Although all four arguments sound illogical and confusing, they are not simple to explain. Aristotle discarded them as fallacies without really showing why.

According to Plato, Zeno had already written a book before his trip to Athens. Unfortunately no work by Zeno has survived. But there is very little evidence that Zeno wrote more than one book.

Virtue is the key to a meaningful and happy life. According to ancient philosophers, Socrates and Aristotle, developing virtue is vital in order to lead a successful, fulfilling life. Although both men differ in interpretations of a “good life,” they both agree that the supreme life is one of virtuous meaning.

Can virtue be taught? The answer to the question is anything but simple. The question is examined in detail throughout Plato’s dialogue called Meno. According to Plato, men cannot be taught anything but knowledge. Therefore, virtue must be a kind of knowledge in order to be taught. This leads to a new question. Is virtue knowledge?
