The discrete light-cone quantization (DLCQ) of a supersymmetric gauge theory in 1+1 dimensions is discussed, with particular attention given to the inclusion of the gauge zero mode. Interestingly, the notorious “zero-mode” problem is now tractable because of special supersymmetric cancellations. In particular, we show that anomalous zero-mode contributions to the currents are absent, in contrast to what is observed in the nonsupersymmetric case. An analysis of the vacuum structure is provided by deriving the effective quantum mechanical Hamiltonian of the gauge (...) zero mode. It is shown that the inclusion of the zero modes of the adjoint scalars and fermions is crucial for probing the phase properties of the vacua. We find that the ground-state energy is zero and thus consistent with unbroken supersymmetry and conclude that the light-cone Fock vacuum is unchanged with or without the presence of matter fields.

Criticism of Sairu s-Salikin, an old Indonesian manuscript on ethics in Islam.

Jonathan Dancy charges that Hutcheson's distinction between justifying reasons and motivating reasons is unimportant: it is simply between moral reasons and other good reasons. I argue that the distinction is between propositions with different presuppositions and different functions. One identifies qualities of objects that we desire; the other identifies qualities that we approve. I situate Hutcheson in the current debate about the nature of practical reasons. I argue that he avoids problems posed for factivists and for Humeans. On Hutcheson's view, (...) motivating and justifying reasons at times refer to the same qualities, which makes it possible for one to serve the function of the other. (shrink)

Louis Frédéric Ancillon was a member of the Prussian Academy of Sciences and Belles Lettres whose imagined dialogue between Berkeley and Hume was read to the Academy in 1796 and published in 1799. It is important as an indicator of the reception of Hume and Berkeley in francophone philosophical circles in late eighteenth-century Prussia. Our introduction is followed by an English translation with notes.

Peirceana provides a forum for the best current work on Peirce worldwide. Besides monographs, the series will publish thematically unified anthologies and edited volumes with a defined topical focus and untranslated English selections of Peirce's writings.

Hobbes would say that this level of apprehension is inevitable in any society that isn't governed by a sufficiently powerful central ruler. Just as in our world, some people or groups would have more power than others, and some of these might have more power than most. The Emperor would still be subject to the demands of the Spacing Guild, for example, while the Spacing Guild would still need to be on good terms with the governor of Arrakis because of (...) the Guild's absolute dependence upon spice. In a world like this, it would be difficult not to see potential threats around every corner, and with good reason. And in this state of wariness, political and social stability will be tough to attain. Hobbes had seen firsthand the terrible destruction that civil war could unleash, the horrific loss of life and destruction of security. (shrink)

ABSTRACT:Daniel Callahan died on July 16, 2019, just short of his 89th birthday. In the years since, we have seen the overturning of abortion rights, a concern central to his scholarship and musings about the place of religion in American civic life. Callahan’s journey from lay Catholic journalist and commentator at Commonweal to a co-founder of the Hastings Center, during his decade of doubt, is especially relevant today as America revisits established precedent governing a woman’s right to choose. His life-long (...) struggle with faith and the secularization of bioethics is a story worth telling, as it may foster dialogue across a divide between religious and laical thinkers that has fractured our political discourse. We recall Callahan’s misgivings about the marginalization of religious perspectives in public life; he sought not the denial of complexity nor of difference in views, but rather the importance of free and honest debate around deeply held beliefs, contextualized in the realities of the contemporary world. Callahan’s ambivalence about his faith remains a part of the fabric of American life, a story that Callahan chronicled to our collective benefit for over a half-century. (shrink)
