"Couples are wholes and not wholes, what agrees disagrees, the concordant is discordant. From all things one and from one all things"

This quote by Heraclitus speaks with the idea of unity and duality. He is recommending that couples, or any two entities, are both whole and not entire. This suggests that while two entities may be separate, they are also linked and based on each other. The idea of agreement and argument is likewise present in this quote. Heraclitus is stating that even when two entities agree, there is still a sense of discord. This is because the arrangement is only possible due to the fact that of the dispute. Lastly, Heraclitus is suggesting that all things come from one source and that one source is the source of all things. This speaks to the concept of unity and interconnectedness. All things are linked and come from the same source. This quote by Heraclitus is a suggestion of the significance of understanding the duality of life and the interconnectedness of all things.
