 Two people walk together down the street and see an approaching dog. One experiences the dog as “Jones’s pet black terrier” while the other experiences it as “a stray mutt that the dog-catchers should take away.” Because of the excessive conceptual differences in their experiencing, constructivist must insist that there was no worthwhile sense in which both observers had the same experience. However, there is a valuable sense in which they are having the same experience: seeing that black dog at that place and time. Similarly, there might exist a valuable commonality of experiences across mystical traditions despite conceptual disparity. The conceptual differences might not be sufficient to deny this important commonality (Wainwright 1981, 25).
