At least three interpretations have been given to B16 of Parmenides' poem. It has been taken for a fragment of his theory of knowledge, of his doctrine of sense perception, and of his views on sensing and knowing. It is usually assigned to the second part of the poem, the Way of Seeming. In this study I will argue that it comes from the first part of the poem, and that it is an affirmation of the close relationship between thought and being.
