What is wrong with man is the measure of all things?

In the attack against Heracleitus and Protagoras, Plato says that they ultimately make man the measure of all things. For what appears to me to be cold may appear to you to be warm. Or what appears to me to be big may appear small to you. No one person may or can have the same perception. Perhaps this is the fault with those who trust that we know thinga by our senses. But, if one percieves a different quality in an object than another one does should we say that truth is therefore subjective? Perhaps the fault lies in our senses. How do we know what is truth? Of course the Bible alone is the word of God. God has revealed the Bible to us. God is truth, logic, and eternal. Therefore, the Bible alone is truth. God alone reveals it.
