Parmenides View

Heraclitus maintained that everything changes. Parmenides rationalized that change was not possible. He believed that change was a deception caused by the senses, and could not be achieved. As a result, our perception of the world is not as it seems. Instead, we can only apprehend the world through logic.

Parmenides also argues that the perception of movement and change is an illusion. He strongly believes in this notion and rationalizes that everything that is, has always been and will ever be, the same. In essence, Parmenides believed that if you speak or think of something, the word or thought relates to something that actually exists. Parmenides assumes a constant meaning of words and concludes that everything always exists and that there is no change. Change cannot happen because everything can be thought of all the time. 

Thus as a conclusion, Heraclitus was wrong in his point of view. Change cannot happen because our senses deceive us. Only logic and reason is possible.
