In this paper, I want to show that continuity is of crucial philosophical significance in Parmenides, who is the first thinker in the West to use the notion of continuity in a philosophically interesting and systematic way, and what being continuous (suneches) means for him. I look in some detail at the three passages in fragment 8 of Parmenides’ poem that are central for Parmenides’ notion of being suneches and discuss whether being suneches refers to something being temporally uninterrupted, spatially (...) connected, or ontologically holding together. An analysis of these three passages shows that suneches for Parmenides implies complete homogeneity and indivisibility. This analysis is also the basis for showing that suneches is conceptualized very differently in Parmenides’ poem and Aristotle’s Physics because of different starting points and different understandings of what we would call the principle of sufficient reason.
