Necessity Lost

A long tradition, going back to Aristotle, conceives of logic in terms of necessity and possibility: a deductive argument is correct if it is not possible for the conclusion to be false when the premises are true. A relatively unknown feature of the analytic tradition in philosophy is that, at its very inception, this venerable conception of the relation between logic and necessity and possibility - the concepts of modality - was put into question. The founders of analytic philosophy, Gottlob Frege and Bertrand Russell, held that these concepts are empty: there are no genuine distinctions among the necessary, the possible, and the actual. In this book, the first of two volumes, Sanford Shieh investigates the grounds of this position and its consequences for Frege's and Russell's conceptions of logic. The grounds lie in doctrines on truth, thought, and knowledge, as well as on the relation between mind and reality, that are central to the philosophies of Frege and Russell, and are of enduring philosophical interest. The upshot of this opposition to modality is that logic is fundamental, and, to be coherent, modal concepts would have to be reconstructed in logical terms. This rejection of modality in early analytic philosophy remains of contemporary significance, though the coherence of modal concepts is rarely questioned nowadays because it is generally assumed that suspicion of modality derives from logical positivism, which has not survived philosophical scrutiny. The anti-modal arguments of Frege and Russell, however, have nothing to do with positivism and remain a challenge to the contemporary acceptance of modal notions.

Philosophers since Aristotle have traditionally held that impossibilities make up the nature of logic. Sanford Shieh investigates an important but underexplored break with this tradition: Frege and Russell questioned whether there really are such things as possibilities or necessities, and sought the foundations of logic elsewhere.

The classic New York Times bestseller about the many forms of loss we experience throughout our lives, and the necessity of letting go. In Necessary Losses, Judith Viorst turns her considerable talents to a serious and far-reaching subject: how we grow and change through the losses that are a certain and necessary part of life. She argues persuasively that through the loss of our mothers’ protection, the loss of the impossible expectations we bring to relationships, the loss of our younger selves, and the loss of our loved ones through separation and death, we gain deeper perspective, true maturity, and fuller wisdom about life. She has written a book that is both life-affirming and life-changing. Drawing on psychoanalysis, literature, and personal experience, Necessary Losses is a philosophy for understanding and accepting a universal human experience. “One of the most sensitive and comprehensive books about the human condition I have read in a long time.” —Harold S. Kushner, author of When Bad Things Happen to Good People “Viorst has synthesized a vast amount of research into a very readable and generous whole.” —The New York Times Book Review
