Response: Twenty years ago, this criticism was a fairly common retort to claims of psi phenomena. Today, with advancements in many scientific disciplines, the scientific worldview is rapidly changing, and the basic limiting principles are constantly being redefined. In addition, the substantial empirical database in parapsychology now presents anomalies that simply won't "go away," thus this criticism is no longer persuasive and is slowly disappearing. Given the rate of change in science today, assigning psi to the realm of the impossible now seems imprudent at best, foolish at worst.
