"Could we have entered into the mind of Sir Isaac Newton, and have traced all the steps by which he produced his great works, we might see nothing very extraordinary in the process"

This quote by Joseph Priestley is referring to the genius of Sir Isaac Newton and his terrific works. Priestley is suggesting that if we were able to enter into Newton's mind and trace the steps he took to produce his works, we would not find anything especially remarkable in the process. This suggests that Newton's genius was not necessarily in the process of developing his works, but rather in the concepts and theories he was able to come up with. Priestley is suggesting that Newton's genius was in his capability to believe outside package and develop advanced concepts that changed the method we consider the world. This quote is a testament to Newton's genius and his capability to think differently and develop groundbreaking theories.
