Introduction
It is important to note that the concept of change was interpreted and understood differently by Parmenides and Anaximenes. On the one hand, the former believed in a static framework of the universe, where any apparent change is a mere illusion. On the other hand, the latter claimed that change is a prime reason for any substance in the world, such as his understanding of air.
Main body
The significant difference in the notion of change between Parmenides and Anaximenes is how essential change is in the universe. Parmenides fully denied the existence of change since he considered it an illusion, and any form of perceived alterations are the inherent part of the process or cycle within the universe. In other words, the philosopher understood nature as a sole static unit with dynamic processes, which result in no change in the unit as a whole. However, Anaximenes believed that change is the only phenomenon that creates diversity and the existence of nature and the universe in general. The philosopher “explains how air is part of a series of changes. Fire turns to air, air to wind, wind to cloud, cloud to water, water to earth, and earth to stone” (Graham, n.d., para. 6). In other words, he believed that all things are comprised of air, where the latter’s change through condensation or rarefaction creates other known matters, such as water, earth, or stone.
Conclusion
In conclusion, Anaximenes has a better explanation of how nature works despite his erroneous assumption that air contains the same substances as other elements. However, his understanding of the dynamics of physical and chemical substances is closer to what one can observe from modern science, such as atoms and molecules being universally shared.
