This two-part volume collects the complete fragments and most important testimonies for the leading presocratic philosophers. The Greek and Latin texts are translated on facing pages and accompanied by a brief commentary for each philosopher.

Explaining the Cosmos is a major reinterpretation of Greek scientific thought before Socrates. Focusing on the scientific tradition of philosophy, Daniel Graham argues that Presocratic philosophy is not a mere patchwork of different schools and styles of thought. Rather, there is a discernible and unified Ionian tradition that dominates Presocratic debates. Graham rejects the common interpretation of the early Ionians as "material monists" and also the view of the later Ionians as desperately trying to save scientific philosophy from Parmenides' criticisms. (...) In Graham's view, Parmenides plays a constructive role in shaping the scientific debates of the fifth century BC. Accordingly, the history of Presocratic philosophy can be seen not as a series of dialectical failures, but rather as a series of theoretical advances that led to empirical discoveries. Indeed, the Ionian tradition can be seen as the origin of the scientific conception of the world that we still hold today. (shrink)

In Science before Socrates, Daniel W. Graham argues against the belief that the Presocratic philosophers did not produce any empirical science and that the first major Greek science, astronomy, did not develop until at least the time of Plato. Instead, Graham proposes that the advances made by Presocratic philosophers in the study of astronomy deserve to be considered as scientific contributions.

This handbook brings together leading international scholars to study the diverse figures, movements, and approaches that constitute Presocratic philosophy. More than a survey of scholarship, this study presents new interpretations and evaluations of the Presocratics' accomplishments, from Thales to the sophists and from theology to science.

According to the traditional view of Empedocles' cosmic cycle, there are two creations of plants and animals, one under the dominion of increasing Strife and one under the dominion of increasing Love. At the point at which Strife holds complete sway the four elements are completely separated and all life is destroyed; at the point at which Love is completely dominant there is also a destruction of the biological world, this time because the elements are blended into a perfectly homogeneous (...) mixture. This interpretation of the cosmic cycle, which has prevailed almost since it was developed by Friedrich Panzerbieter and seconded by authority of Eduard Zeller was challenged by Paul Tannery and then by H. von Arnim . Long after these essentially programmatic critiques, three independent studies published in 1965 by Jean Bollack, Uvo Hölscher and Friedrich Solmsen mounted a vigorous challenge to the received view. However, in a detailed monograph devoted to Empedocles' cosmic cycle, Denis O'Brien brought to bear an impressive array of scholarly evidence and critical acumen in support of the traditional view . Several challenges to the traditional view have appeared since O'Brien's book, of which the most significant is that of A. A. Long, who, while criticizing attempts of some opponents of the traditional view, produced some novel and interesting arguments against it. Although the traditional view continues to enjoy the support of authorities such as Jonathan Barnes and M. R. Wright, there is a decided shift in favour of revisionary views. Nevertheless recent advocates of a revisionary interpretation do not provide detailed refutations of the traditional view; Long's arguments remain the strongest objections to the traditional view, and they have never been refuted. Will they stand up to scrutiny? (shrink)

In this study, Daniel W. Graham addresses two major problems in interpreting Aristotle. First, should we reconcile the apparent inconsistencies of the corpus by assuming an underlying unity of doctrine, or by positing a sequence of developing ideas? Secondly,what is the relation between the so-called logical works on the one hand and the physical-metaphysical treatises on the other? Although the problems appear to be unrelated, Graham finds that the key to the first lies in the second, and in doing so (...) provides the first major alternative to theunitarian approach since Jaeger's pioneering developmental study of 1923.

In Philolaus’ cosmology, the earth revolves around a central fire along with the other heavenly bodies, including a planet called the counter-earth which orbits below the earth. His theory can account for most astronomical phenomena. A common criticism of his theory since ancient times is that his counter-earth does no work in the system. Yet ancient sources say the planet was supposed to account for some lunar eclipses. A reconstruction of Philolaus’ cosmology shows how lunar eclipses occurring at certain times (...) of day cannot be explained by earth blocking the sun’s light. The counter-earth could explain these eclipses. (shrink)

This article is concerned with the first philosophers and scientists in the Western tradition. It studies the Presocratic philosophers. One can approach early Greek philosophy through either particular figures of the period or thematic studies that cover broader time periods. If the term “Presocratic philosopher” is a conventional designation established by scholars, it marks out a set of figures who do seem to merit special attention. So as long as there is a tribe of philosophers in the West, they will (...) look back to the first antecedents of their profession. And it seems that the Presocratics are the obvious candidates for founders of the movement. (shrink)

The founder of atomic theory, according to Aristotle and Theophrastus, is Leucippus. His very existence has been called into question. Three of the best minds of nineteenth-century scholarship were embroiled in a vehement debate on this question, which thereupon became a cause célèbre, with scholars weighing in on both sides for the next half century. Ultimately this debate seems to have ended in stalemate and exhaustion rather than in any clear-cut decision. After briefly reviewing the debate, this article argues that (...) there are indications of an atomic theory different from Democritus's that can plausibly be attributed to Leucippus. It considers indications that the atomic theory was known in the mid-fifth century, and then tentatively explores Leucippus's contributions to atomism in a way that will illuminate Democritus's contributions.

Daniel Graham offers a clear, accurate new translation of the eighth book of Aristotle's Physics, accompanied by a careful philosophical commentary to guide the reader towards understanding of this key text in the history of Western thought. It is the culmination of Aristotle's theory of nature: he explains motion in the universe in terms of a single source and regulating principle, a first `unmoved mover'.

A meteor that fell in northern Greece in 467 BC was said to have been predicted by Anaxagoras. It seems rather that his theory entailed (“predicted”) the possibility of such bodies. The meteor provided a rare case of an observation confirming a theory. The subsequent recognition of the meteor shows that early philosophical theories could have testable consequences and that empirical evidence was being sought to evaluate theories at this early time.
