Spinoza and the Logical Limits of Mental Representation

This paper examines Spinoza’s view on the consistency of mental representation. First, I argue that he departs from Scholastic tradition by arguing that all mental states—whether desires, intentions, beliefs, perceptions, entertainings, etc.—must be logically consistent. Second, I argue that his endorsement of this view is motivated by key Spinozistic doctrines, most importantly the doctrine that all acts of thought represent what could follow from God’s nature. Finally, I argue that Spinoza’s view that all mental representation is consistent pushes him to a linguistic account of contradiction

The Nozick Game

In this article I introduce a simple classroom exercise intended to help students better understand Robert Nozick’s famous Wilt Chamberlain thought experiment. I outline the setup and rules of the Basic Version of the Game and explain its primary pedagogical benefits. I then offer several more sophisticated versions of the Game which can help to illustrate the difference between Nozick’s libertarianism and luck egalitarianism

Spinoza and the problem of other substances

ABSTRACTMost of Spinoza’s arguments for God’s existence do not rely on any special feature of God, but instead on merely general features of substance. This raises the following worry: those arguments prove the existence of non-divine substances just as much as they prove God’s existence, and yet there is not enough room in Spinoza’s system for all these substances. I argue that Spinoza attempts to solve this problem by using a principle of plenitude to rule out the existence of other substances and that the principle cannot be derived from the PSR, as many claim.Abbreviation: PSR: Principle of Sufficient Reason

NATO at 60: A Hollow Alliance

As the North Atlantic Treaty Organization celebrates its 60th birthday, there are mounting signs of trouble within the alliance and reasons to doubt the organization's relevance regarding the foreign policy challenges of the 21st century. Several developments contribute to those doubts. Although NATO has added numerous new members during the past decade, most of them possess minuscule military capabilities. Some of them also have murky political systems and contentious relations with neighboring states, including (and most troubling) a nuclear-armed Russia. Thus, NATO's new members are weak, vulnerable, and provocative -- an especially dangerous combination for the United States in its role as NATO's leader. There are also growing fissures in the alliance about how to deal with Russia. The older, West European powers tend to favor a cautious, conciliatory policy, whereas the Central and East European countries advocate a more confrontational, hard-line approach. The United States is caught in the middle of that intra-alliance squabble. Perhaps most worrisome, the defense spending levels and military capabilities of NATO's principal European members have plunged in recent years. The decay of those military forces has reached the point that American leaders now worry that joint operations with U.S. forces are becoming difficult, if not impossible.The ineffectiveness of the European militaries is apparent in NATO's stumbling performance in Afghanistan. NATO has outlived whatever usefulness it had. Superficially, it remains an impressive institution, but it has become a hollow shell -- far more a political honor society than a meaningful security organization. Yet, while the alliance exists, it is a vehicle for European countries to free ride on the U.S.military commitment instead of spending adequately on their own defenses and taking responsibility for the security of their own region. American calls for greater burden-sharing are even more futile today than they have been over the past 60 years. Until the United States changes the incentives by withdrawing its troops from Europe and phasing out its NATO commitment, the Europeans will happily continue to evade their responsibilities. Today's NATO is a bad bargain for the United States. We have security obligations to countries that add little to our own military power. Even worse, some of those countries could easily entangle America in dangerous parochial disputes. It is time to terminate this increasingly dysfunctional alliance

Solid sorbent air sampler

A fluid sampler for collecting a plurality of discrete samples over separate time intervals is described. The sampler comprises a sample assembly having an inlet and a plurality of discreet sample tubes each of which has inlet and outlet sides. A multiport dual acting valve is provided in the sampler in order to sequentially pass air from the sample inlet into the selected sample tubes. The sample tubes extend longitudinally of the housing and are located about the outer periphery thereof so that upon removal of an enclosure cover, they are readily accessible for operation of the sampler in an analysis mode
