Heraclitus was a great Greek philosopher who lived at the end of the sixth century B.C., Heraclitus criticizes his predecessors and contemporaries, and affirmed the existence of a word of eternal character, logos, word that according to his knowledge meant that all things are one, in a certain sense. He believed that opposites are necessary for daily life, but that they were unified in a system of balanced exchanges. For him, the world itself consisted of an exchange of elements similar to law, which was symbolized by fire, which is why the world should not be identified with any particular substance, but rather with a continuous process governed by a law of change. This law had underlying laws of nature that manifested themselves as a moral law for human beings. Heraclitus was the first Western philosopher to go beyond physical theory in search of metaphysical foundations and moral applications.
Greek philosopher oriented towards the search for a common constitutive principle of plurality in beings that inhabited nature and based his theory on the fact that opposites were necessary for life and that they were united in an exchange system.
Heraclitus lived in the city of Ephesus, an important place on the Ionian coast of Asia Minor, considered the cradle of philosophy. Apparently, he came from an aristocratic family, although not much is known about his life other than what can be deduced from his own statements, since all the ancient biographies of him consist of nothing more than inferences or imaginary constructions based on his sayings. He used the nickname “the dark one” because of the enigmatic character of his style. He was against Athens democracy and was part of a sympathetic group with the Persian king Darius I the Great.
Heraclitus thought that the vast majority of human beings lacked understanding. For him, most people walk through life without even understanding what was going on with them or their lives. However, he also believed that the experience of words and deeds was able to enlighten those who were receptive to their meaning. On the one hand, he praised the sensitive experience, preferring the things he had seen, heard or experienced, and on the other, he considered the eyes to be the bad witnesses of men if they had barbaric souls. A barbarian is one who does not speak Greek. Therefore, he believed that, although sensory experience was necessary for understanding, if the correct language was not known, there was no way to interpret the information provided by the senses. He also considered that fire had a constituent role to things and was the reason for all the changes that occurred in nature.
His contributions to philosophy and science created a precedent for Greek philosophical thought, better known as Socratic thought. Some of their contributions were:
Some of his fragments are:
For Heraclitus the arche is the fire, which is a substance generating the beginning of things, of the cosmos. The universe was an eternal fire that was lit and extinguished by the logo, with which the order and harmony of the cosmos could be given, and of laws that determined unity and struggle.
Apparently Heraclitus could only write a book titled “Of Nature”, of which there are three subdivisions:
