  What chance is there then to learn the secrets of the world?  Heraclitus is not wholly pessimistic about human cognitive abilities: “All men have a share in self-knowledge and sound thinking” (B116). What is needed is not simply more sense experience or more information, but an improved way of comprehending the message (logos) that the world offers. In this context his curious method of expression begins to make sense. He presents his statements in the form of puzzles, riddles, aperçus.  Many of them support two or more readings, and contain hidden insights. To comprehend them the reader must grasp their complexity and then discover their unity. To read Heraclitus appropriately is to have a rich cognitive experience, as the philosopher hints in his introduction (B1).
