Nicholas Jardine offers here an edition and the first translation into English of Johannes Kepler's A Defence of Tycho against Ursus. He accompanies this with essays on the provenance of the treatise - the circumstances which provoked Kepler to write it, an analysis of its strategy, style and historical sources and of the contents of Ursus' Treatise on Astronomical Hypotheses to which Kepler was replying. Dr Jardine also provides three extended interpretive essays on the intrinsic interest and historical significance of the work.
Review of the hardback:: 'Jardine's book is rich in epistemological and historiographical issues, bold and stimulating in its speculations and detailed in its use of evidence. It should lead to further fruitful investigation ... few will deny the substantial contribution made by its author to our understanding of the origin of Kepler's advanced conceptions ...' Isis Review of the hardback: 'Jardine's elucidating and profound essays deserve a wide audience.' Annals of Science Review of the hardback: '... its importance in Kepler's scholarship has been recognised for many decades and Jardine's book at last brings it to light ... Jardine's translation ... is lucid and meticulously annotated. [His] essays are remarkable for their intrinsic human as well as scholarly interest.' Philosophy of Science
