A theory predicts that the mean age of stars within a particular type of star cluster is 3.3 billion years‚ with a standard deviation of .4 billion years. (Their ages are approximately normally distributed.) You think the mean age is actually greater‚ and that this would lend support to an alternative theory about how the clusters were formed.

pure practical reason to ‘‘frame the Rational with the Reasonable.’’ As seen in the Dewey Lectures Rawls emphasizes that ideal agents are not only rational‚ but must also reasonable. Rationality for Rawls carefully calculates the means which lead to certain ends‚ which may be traced to Kant’s hypothetical imperative or what Rawls terms empirical practical reason. Ideal moral agents not only learn how to achieve ends efficiently or rationally‚ but also how to achieve such ends by employing a moral
