The heavily studied philosophical debate that has been carried for centuries on the nature of being and the perception of it, displays the vast differences between the two philosophers Heraclitus and Parmenides. One which believed in a singularity of things, while one differs and carries the philosophy of a duality of reality. One that believes that the changes in perception are deceitful, while the other displays a philosophical view that our perceptions essentially relative and always changing based one of nature. One believes that reality and nature is constant , while the other believes that everything is constantly changing , and that even the flowing river that one may step his foot in will not be the same river the next time around.

Science and physics( which is an arm of philosophy tells us that when force is applied to things there is the possibility of a change in the molecular make up of the item. It is like a formless matter. Once the matter has been molded into a particular form it is more than likely to lose atoms during the process. I believe the example of the flowing river is a pretty clever one. Being that the river is ever flowing there is constant erosion occurring as the constant (the bed of the river) interacts with the moving (the flow of the water). In actuality even the small acts such as shaking hands involves the exchange of atoms and molecules.
Parmenides presented a conflicting philosophical opinion to that of Heraclitus. Parmenides presented the view that the state of being in nature is constant. It does not change and that our perception of reality may at times be very deceitful. While I do not agree with this in regards to the state of being and nature I do think this argument would hold much weight and would be considered a solid truth in terms of psychology. A person’s psychological makeup could very well affect the way
