Edna Ullmann-Margalit on Presumptions and Defeasability

Go

Given my focus on practical rather than theoretical reasoning, I may at this point consider weakening the principle of total evidence and examining a presumption instead. The presumption to be examined establishes, for purposes of rational action, a generic bias in favor of more knowledge rather than on less. To defend the adoption of the presumption in favor of being maximally informed amounts to defending the belief that following it will lead, in the long run, to better overall results, in terms of goal fulfillment, than the results of following its antithesis (i.e., a presumption establishing a generic bias in favor of acting on the basis of less knowledge rather than on more), or indeed better than the results of a case-by-case balancing (i.e., of following no rule or presumption at all).

Complex Cause

Go A single cause is identified when the effect is actually caused by a number of interacting objects or events.

Insignificance

Go One thing is held to cause another, and it does, but it is insignificant compared to other causes of the effect.

Joint Effect

Go One thing is held to cause another when in fact both are the effect of a single underlying cause.

William Lane Craig on the Unnecessary Universe

Go

Both cosmology and philosophy trace their roots to the wonder felt by the ancient Greeks as they contemplated the universe. The ultimate question remains why the universe exists rather than nothing. This question led Leibniz to postulate the existence of a metaphysically necessary being, which he identified as God. Leibniz’s critics, however, disputed this identification, claiming that the space-time universe itself may be the metaphysically necessary being. The discovery during this century that the universe began to exist, however, calls into question the universe’s status as metaphysically necessary, since any necessary being must be eternal in its existence. Although various cosmogonic models claiming to avert the beginning of the universe predicted by the standard model have been and continue to be offered, no model involving an eternal universe has proved as plausible as the standard model. Unless we are to assert that the universe simply sprang into being uncaused out of nothing, we are thus led to Leibniz’s conclusion.

Bettijane Levine & Eli Wiesel on Evil

Go

After years spent studying the world’s great philosophers and writers, of poring over the Bible, Talmud, Torah and other ancient texts, of discussions with inspired social and religious leaders, [Eli] Wiesel
still has no answer to the question of what makes people good or evil. “I can give all the usual answers — education, home, parents, peer pressure. But these are just factors. The mystery of why people become
good or evil is still just that — a mystery.” But he has thought of one “rational approach” to ensuring more goodness in humanity. It is respect. “If I respect The Other for whatever The Other is, and The Other respects me for whatever I am, then there can be understanding and even great friendship between all people.”
