Greek and Roman Philosophy
The basic principles of Greek and Roman philosophy include the belief in change and the existence of the "Logos" or logic, which structures everything. For example, Heraclitus believed that the human soul was part of the universal fire, and Parmenides posited that there is no fixed structure. In addition, the philosophy of Heraclitus focuses on the division of the world into four constitutions, one for each element.
Parmenides is a pivotal figure in the history of philosophy. He challenged the physical systems of his predecessors and outlined the metaphysical criteria for a successful system. He is often associated with Eleatic philosophers such as Zeno of Elea, Melissus of Samos, and Xenophanes of Colophon, who were all highly controversial. Parmenides argues that his axioms are superior to any possible mortal accounts of the cosmos.
Some scholars disagree about the exact date of Parmenides' birth. There are two competing methods, with the oldest dating the philosopher to about 540 B.C.E. The more reliable method dates Parmenides to about 515 B.C.E. However, it is possible to find other sources that suggest he was born in a slightly different year than his actual birthdate.
The text is fragmented. While the earliest known copy of the poem is called "On Nature," this title is highly suspect. Sextus gave this generic title to all Presocratic works. In any case, scholars have assembled purported quotations from Parmenides and arranged them according to internal and external evidence. The poem is comprised of 154 lines of dactylic hexameter. Some are complete, others are partial or one word.
The early Greek philosophers had three main characteristics. First, they sought to understand the world in natural terms. Second, they sought to guide our conduct by understanding the nature of reality and human behavior. And third, they stressed critical thinking. The emphasis was on examining the foundations of philosophical ideas. The Greeks and Romans had very different ways of approaching the world. In each case, they sought to answer these questions.
Empedocles' doctrine of eternal return
The teachings of Empedocles' doctrine of eternal return are largely based on his cosmology, which describes him as a daimon who lives a long life, commits sins, and is destined to die. Upon his death, he must reincarnate into different forms of nature. Empedocles' doctrine has been widely regarded as a powerful and important philosophy, and has many aficionados today.
Empedocles was a renowned Greek philosopher, poet, and statesman. He was the last Greek philosopher to write philosophy in epic verse. His two poems, On Nature and Purifications, have survived in large part. The De Rerum Natura is the first of the great philosophical poems. The fragments of his writings are found scattered throughout the world. Empedocles' writings are based on a cosmology of time and eternity, which empedocles formulated in the 3rd century BC.
The four-element theory of matter attributed to Empedocles has been used in the development of particle physics. Empedocles used the botanical metaphor of roots to emphasize the creative potential of roots. Empedocles also used the Latin word elementa to refer to the elements of matter. This stress on the interchangeability of the elements also helps explain why we can see objects and people through a microscope.
Another doctrine of eternal return originated from Empedocles. In his cosmology, the soul is transmigrated between elements and is constantly tossed from one to another. In ancient Greece, this belief remained popular throughout the centuries. For instance, one can find the soul of a dead friend in the yells of pain of a dog. But a person who died while he was still alive could be reincarnated in another form.
Heraclitus' belief in fire as the primary element
Heraclitus was a Greek philosopher born in about 540 BCE. He believed that fire and energy were essential to the creation of the world and rejected the water and air theories. His theory centered on the concept of the Logos and his three-word utterance. The following is a brief description of his beliefs and the importance of fire in Greek & Roman philosophy.
According to Heraclitus, fire was the primary material that unites all things. He described the world order as being like an "ever-living fire" and extended its manifestations to the ether, the upper atmosphere. Fire, he explained, turns into the earth and ocean, and each of these two equal masses return to their respective aspects of fire and water. This dynamic equilibrium maintains a world in order.
Heraclitus' belief in fire as a primary element is fascinating, but there are a lot of questions to be answered. First of all, what is fire? Is it a substance, or is it an energy? Heraclitus was an astrologer and philosopher. He developed the ideas of Xenophanes, who believed in an eternal God at the root of all things. He called this force Logos.
According to Heraclitus, the world is ultimately made of fire, and there is no change in that fact. He was the first philosopher to use fire as a metaphor for change, and he used fire to prove his point. He also contrasted himself with Parmenides, who believed in a static world. In a sense, we can understand Heraclitus' views in light of these ideas.
Heraclitus' classification of constitutions
Heraclitus' classification of constitutions was a response to his Ionian predecessors, Thales, Anaximander, and Anaximenes, who argued that all things come from a single source, the original stuff. He believed that this world is a rationally structured order of various stuffs. But the Miletians believed that all things originate from a single source, and that we have been shaped by the same stuff since it was created.
In the early fifth century BC, the Ionian philosopher Heraclitus lived in Ephesus, a city on the modern-day Mediterranean coast. He had a reputation for a profound melancholic mood, but he was also known for his honesty, magnanimity, and broad mind. He is regarded as one of the greatest pre-Socratic philosophers, leaving more than a hundred epigrammatic fragments. His philosophy was characterized by a unique style of expression that combined concrete examples with general truths.
Heraclitus lived during the sixth century BCE, and while he does not speak about politics, his ideas are nonetheless reminiscent of the views of the Greek aristocracy. He was not aristocratic, but he did share a preference for the rule of a few wise men over the mass of people. He even recommends citizens hang themselves rather than follow the aristocratic rule.
Heraclitus' rejection of cosmic justice is notable. He rejects the idea of cosmic justice, where opposites must suffer for transgressions. However, he does recognize the importance of a constant clash of opposites, a process that would be impossible without life. He also says that death is a necessary precondition for life. The aristocracy would have no place in the world without this constant struggle between opposites.
In his apeiron, Heraclitus teaches that knowledge is not his own. Instead, it is a timeless truth that exists in the world, and Heraclitus tries to pass it along to his audience. He says that knowledge is not a gift, but it is a necessity. The apeiron teaches that knowledge is power, and that understanding can be a virtue.
To be able to understand Heraclitus's apeiron, we must first grasp his goal in writing. He aims to explain the nature of things, or the relation between opposites. He defines nature as "the character of an object, the relation of opposing properties in that object." This discussion of nature is the true significance of the fragments, and it represents a distinctive thesis among the many concerned with opposition.
As we have seen, God is not a person, but a divine agent, and the apeiron is his way of linking the divine and the character. God is not a 'personal agent' like the apeiron, but is rather an 'unique and enduring' concept. And the apeiron connects the divine with the apeiron, and this is a major distinction in Heraclitus' apeiron.
The fire that Heraclitus described as an aphorism may apply to elemental fire. He characterized fire as a representation of the kosmos, and thus as having the properties of both motion and rest. And, since fire was the object of his study, he may have been motivated by the notion of the 'harmonious union of opposites.' It is unclear whether or not Heraclitus actually intended the aphorism to apply to elemental fire.
