Hello my name is Chase I hope your having a good day. Here's my Answer

Items that are used as money often have little value in and of themselves. For example, the paper used to print money is not particularly valuable. Money has value because it is an exchange medium that people understand and accept as such. When everyone accepts that a bill or a coin has value, people can use it as a form of payment to purchase goods or services. Before money existed, people used other systems to perform exchanges.

Bartering involves a direct trade for goods and services. Although some aspects of this transaction are similar to the exchange of money, bartering required time as people hammered out the terms of the deal. Utilizing money as the medium for trade simplified transactions significantly. Trade and barter were precursors to the monetary system used in today's society. Although trade and barter may seem almost archaic, they were the business solutions for people who lived before the convenience of credit card processing.

from thales, who is often considered the first western philosopher, to the stoics and skeptics, ancient greek philosophy opened the doors to a particular way of thinking that provided the roots for the western intellectual tradition. here, there is often an explicit preference for the life of reason and rational thought. we find proto-scientific explanations of the natural world in the milesian thinkers, and we hear democritus posit atoms—indivisible and invisible units—as the basic stuff of all matter. with socrates comes a sustained inquiry into ethical matters—an orientation towards human living and the best life for human beings. with plato comes one of the most creative and flexible ways of doing philosophy, which some have since attempted to imitate by writing philosophical dialogues covering topics still of interest today in ethics, political thought, metaphysics, and epistemology. plato’s student, aristotle, was one of the most prolific of ancient authors. he wrote treatises on each of these topics, as well as on the investigation of the natural world, including the composition of animals. the hellenists—epicurus, the cynics, the stoics, and the skeptics—developed schools or movements devoted to distinct philosophical lifestyles, each with reason at its foundation.

with this preference for reason came a critique of traditional ways of living, believing, and thinking, which sometimes caused political trouble for the philosophers themselves. xenophanes directly challenged the traditional anthropomorphic depiction of the gods, and socrates was put to death for allegedly inventing new gods and not believing in the gods mandated by the city of athens. after the fall of alexander the great, and because of aristotle’s ties with alexander and his court, aristotle escaped the same fate as socrates by fleeing athens. epicurus, like xenophanes, claimed that the mass of people is impious, since the people conceive of the gods as little more than superhumans, even though human characteristics cannot appropriately be ascribed to the gods. in short, not only did ancient greek philosophy pave the way for the western intellectual tradition, including modern science, but it also shook cultural foundations in its own time.
