Optical Theories & Optical Correspondence

To appreciate many of Newton's writings on optics fully, it is essential to be aware of the contemporary comments and criticisms to which Newton was responding. He was particularly incensed at having the accuracy of his observations queried by two French Jesuits, Francis Linus and Ignace Pardies. In fact, both men had misunderstood Newton's essay and he had little difficulty refuting them: Linus frankly admitted defeat, and Pardies died before Newton's reply was published. More serious were the reservations expressed by two of the few individuals who could be said to belong in Newton's intellectual league, Christiaan Huygens and the Royal Society's own Curator of Experiments, Robert Hooke. Huygens considered that Newton's data, although interesting, did not warrant the inferences he drew from it. Hooke objected that Newton had not conducted enough experiments and that other theories (i.e. his own) could explain the phenomena equally well. The deeply neurotic Newton took great exception to these criticisms and repeatedly threatened to withdraw from public discussion of natural philosophy altogether. However, this did not stop him from engaging in intermittent but increasingly bitter semi-public feuds with Hooke until the latter's death in 1703.

Despite Newton's often-proclaimed detestation of such controversies, these critical reactions to his optical writings played a vital role in stimulating his thought by spurring him to refine and elaborate his theories. This page presents Newton's writings within this larger context. It offers three of Newton's optical manuscripts followed by the shorter essays written against his theories as well as Newton's responses to them. So far as possible, these printed works are listed in the order of their composition (which is not always the same as the order of their publication), in order to make it possible to follow the progression of these disputes over time.
