In his new book A Defense of Hume On Miracles, Robert Fogelin defends one of the 18th century's most profound philosophers from recent attacks on one of his most important pieces. Fogelin's book begins by recapping Hume's arguments on how to evaluate the veracity of claimed miracles. Using academic but readable prose, Fogelin first introduces Hume's theories. Hume argued that testimony is needed to judge whether a miracle has truly happened. Ultimately, determining which testimony is trustworthy provides the greatest difficulty. Hume held extremely high standards for such reliable testimony: He believed that based on his standards, no miracles had yet met his standards and none were likely to do so. Fogelin contends that recent critics have tried to unfairly undermine Hume's theories. Hume is portrayed by some as making circular arguments, like "if a miracle did occur, its occurrence by nature would prove it to not be a miracle." Two in particular, David Johnson and John Earman, have recently published attacks on Hume's theories. Responding to these challenges, Fogelin carefully and systematically addresses how these critics' arguments have mischaracterized Hume's intentions, rendering their challenges irrelevant. An example of Fogelin's analytical writing can be seen in this excerpt, describing the 'reverse' method for evaluating testimony, in which evidence is critiqued based on its lack of common sense and truthfulness:
[C]onsider a report from a "normally reliable source" that President George W. Bush has been observed walking a tightrope over his swimming pool. Most people's initial reaction would be justified disbelief. The sheer bizarreness and improbability of such an event's taking place cast immediate doubt on the force of the testimony offered in its behalf. It seems more reasonable to treat the report as a hoax or perhaps as a misunderstanding of a political metaphor. This is a simple, and I believe uncontroversial, example of the reverse method at work.

Walking The Tightrope Of Reason: The Precarious Life of a Rational Animal.

In Walking the Tightrope of Reason, Robert Fogelin explores the human tendency to take extreme and often dangerous positions when trying to make sense of the universe. He begins by looking at the law of noncontradiction. The law says that something cannot be two opposing things at once. Fogelin argues both for and against this law in his first two chapters. By presenting both sides of the argument, Fogelin underscores some of the problems associated with philosophical inquiry. In the next chapter he explores two responses to this problem. The first one, dialectical illusion, an idea first introduced by Immanuel Kant, is the idea that when confronted with philosophical questions we can't solve, we create answers even if these answers do not adequately answer the question. The second response is skepticism. While Fogelin notes that skepticism is necessary to a degree, he also points out that it can be dangerous if taken to extremes. Reflecting on the works of thinkers like Kant, David Hume, Ludwig Wittgenstein, Friedrich Nietzsche and Walt Whitman, Fogelin offers what he calls "modest suggestions" in the final chapters to confront the problems introduced in the beginning of the work:
I have suggested that the only thing - or at least the chief thing - that protects us from falling into incoherence, from being captured by dialectical illusion, and from succumbing to an abject skepticism is becoming engaged in the world in ways that put our thoughts under constraints that are not themselves further thoughts. This is an inherently fallible, risky, and often disappointing activity. It is not, however, an inherently dull activity. It is often fun and, at its best, high adventure.

The Neurolab Spacelab Mission: Neuroscience Research in Space

In their new book The Neurolab Spacelab Mission, Jay Buckey and Jerry Homick offer a study that combines physical and neurobiological science. In a series of articles that shows the results of 26 experiments conducted in space, they examine how weightlessness affects the brain. The book emphasizes changes in the balance system, the nervous system, and in body navigation and blood pressure. The 16 days of experiments were conducted by seven members of the flight crew and two alternate payload specialists in the control center, and involved several animals. One experiment consisted of catching a falling ball in weightlessness. The results showed that humans rely on two factors to foresee the motion of a falling object: while incorporating sensory information, we also use an internal model in the brain to predict gravity's effect on the object. Another experiment raised rats in microgravity and compared them to control rats reared on earth. The results suggested that an animal's motor system develops differently according to the environment: the brain structure differed between these two groups of rats, and the flight rats had trouble turning themselves upright when they were turned upside down. Buckey, who was on the Neurolab mission, describes the results of surgery on rats:
For Neurolab, the procedures and techniques to perform recovery surgery were developed and used for the first time in space. Five 21-day-old rats were anesthetized, and their soleus and extensor digitorum longus leg muscles were injected with label. The surgical incisions were closed with wound adhesive. All rats tolerated the procedure well, and they all recovered uneventfully. The wound sites were healing cleanly when examined two days after the surgery. The procedures worked well and demonstrate that, if needed in the future, challenging and delicate surgical procedures can be performed in space.
