Democritus of Abdera:
(Ancient Greek: Δημόκριτος, Dēmókritos; c. 460 BC – c. 356 BC).Greek philosopher, astronomer, mathematician and traveller. He is counted among the presocrats and was known as ‘the laughing philosopher’. Together with his teacher Leucippus, he was the founder of atomism, with which they responded to the Eleates. According to atomism, the cosmos consisted of emptiness (the non-existent) and bodies (atoms, the existing) in an infinite space. Those bodies are eternal and can move. Democritus wrote a lot: sixty titles are known. These dealt with ethics, natural philosophy, mathematics, music, poetry and technical themes. Of these, mainly some ethical theses have survived
