  In his fragments Heraclitus does not explicitly criticize the Milesians, and it is likely that he saw them as the most progressive of previous thinkers. He does tacitly criticize Anaximander for not appreciating the role of injustice in the world (B80), while he might have expressed some admiration for Thales (B38). His views can be seen to embody structural criticisms of Milesian principles, but even in correcting the Milesians he built on their foundations.
