Kuhn thought that there exists no external standard of rationality that we could appeal to in order to answer this question, but he also held that science is the very epitome of rationality (Kuhn 1971, 143f).
According to one such prominent theory of 'external rationality', capacity should be defined as the ability to make rational decisions, in this external sense (Culver & Gert 2004, 265).
The internal state of a system tends to be richer in terms of intentionality and rationality than its external state.
The other external support for morality is a feature of rationality itself: that it cannot depend on the egocentric vantage point of the reasoner.
In addition, the results of internal validations of bootstrapping and Y-randomization confirmed the rationality and good predictive ability of the model, as well as external validation (the external predictive correlation coefficient r2ext = 0.629).
She is neither under any external constraint (like the law), nor under internal demands (of rationality or of the Kantian moral law).
Nevertheless, cognitions derive their status as thoughts capable of rationality from the fact that they have objects which represent the external world.
Retrospective rationality theories, unlike theories that assert that behavior is prospectively rational and consciously chosen to obtain some goal, suggest that behavior is largely under some external control and behavior is rationalized after the fact (e.g. Aronson 1972).
The experimental results verified the rationality and validity of the diffusion model proposed in this study, considering the coupling effects of external sulfate attack and loading condition.
Not surprisingly, it is the technocratic revolution and the rise of the managerial class - a class that is less creative, risk-averse, and tends to relinquish leadership in the face of external economic forces -- that is at the root of this spectacular failure of aptitude and disconnect from rationality.
Since the early 70's, however, a large body of empirical research undertaken by social and cognitive psychologists shows that in many social contexts external rewards, typically monetary ones, affect behavior in a direction opposite to that predicted by a standard selfish-rationality argument.
