"Above all, a man of inexhaustible energy, drawing life with full handfuls and a great provocateur. However, in the good sense of the word. As he admitted in an interview with me, which we published as a book, he felt almost all his life a fool who wanted to make people laugh and at the same time stimulate them to think. Anyone who has ever listened to the lecture of Professor Vetulani, knows what I'm talking about. That's why I find it so difficult to accept His death. Unreasonable, because it is a consequence of a tragic accident. I could not be present at his 80th birthday, so I was hoping to celebrate the 85th and then the 90th and subsequent jubilees with his family and lots of friends. I was hoping to see him during these jubilees, bursting with energy and wit, as He did usually. Unfortunately, life has written a different scenario."

“He is an outstanding pharmacologist and at the same time a man who is obsessed with popularizing – in the best sense of the word. He does it great, gathering thousands of listeners on various occasions.”

“A truly Renaissance personality. Absolutely undisputed authority, world-renowned scholar, a real neuroenthusiast who can also spray such a cascade of wit and humor that all anecdotes should hide!”

“Empathy and aggression – although seemingly very distant from each other – have a largely similar neurobiological background and are often intertwined. Besides, our entire legal system is based on the fact that excessive empathy activates centers of aggression.”

“As I walk through my beloved Krakowski Park and pass by a group of young people from which I can smell beer, I give them a wide berth. But when I feel the weed, I go boldly through their group and sometimes chat. Yes, the abuse of marijuana causes trouble with memory, concentration, but it is a short-lived condition. I'm not talking about extreme cases, but there are few of them. Less than after alcohol. Oneself should sometimes detach from reality to deal with it somehow.”

“I met Jurek many years ago when he was only little older than his beloved grandson now. And he was just as nice and at the same time extremely handsome!”

“With all due respect for the title of professor. Vetulani, however, is a unique moron.”
