QUESTIONS FOR THE COSMOS
LEAD: TO THE EDITOR: Congratulations to Prof. Robert Jahn of Princeton for having the courage to pursue his investigation of psychic phenomena ('Questions for the Cosmos,' by Steve Fishman, Nov. 26). That is exciting. But as one who has participated in informal experiments testing such things as telepathy and psychometry (with startling results) and as someone who has read widely in the literature, I would ask: How many times do we have to prove that ESP exists?

That is exciting. But as one who has participated in informal experiments testing such things as telepathy and psychometry (with startling results) and as someone who has read widely in the literature, I would ask: How many times do we have to prove that ESP exists? And when are we going to spend more of our resources investigating how and why it happens? Those surely are the questions we should be asking.  GRACE E. HINRICHS  Canandaigua, N.Y
