What is your reaction to Kellys constructive alternativism

What is your reaction to Kellys constructive alternativism? What do you think about the idea that there may be no objective reality or absolute truth to discover? Can we conduct a science of persons if there is no objective reality or truth to discover? Think about a time in which you viewed a situation in one way and someone else saw the situation much differently. Do you think there was a reality to be discovered in that situation, and if so, how would someone go about determining what was real and what was not?
