 The fragments of Timon also emphasize Pyrrho’s exceptional tranquility, and add a further, more philosophical dimension to it. Several fragments suggest that this tranquility results from his not engaging in theoretical inquiry like other philosophers, and with his not engaging in debate with those philosophers. Other thinkers are perturbed by their need to discover how the universe works, and their need to prevail in arguments with their rivals; Pyrrho is unconcerned about any of this.
