Since we do not even know in most cases what a non-circular reason for demonstrating superiority would look like, the "only rational course" for an exclusivist "is to sit tight" with the beliefs "which [have] served so well in guiding [her] activity in the world".
This circular reasoning fails to acknowledge that the reason for complications with multiple attempts is, in fact, the presence of drug-induced apnea producing hypoxemia.
That's circular reasoning.
Walker appears to be employing some serious circular reasoning here, claiming that weed -- which is illegal, obviously -- is less socially acceptable than alcohol, which is (he seems to be saying) one reason it should remain illegal.
The questions appear to have originated on an anonymous circular, thus the reason for the answers to be presented in the same manner.
A reasonable reason is related to the category of photons in the co-circular channel.
Asteroids going round a star in nice, circular orbits, he reasons, will not have much cause to collide.
For these reasons, a circular approach could allow the newer wave of fast growing economies around the world to leapfrog the west's historically inefficient approach to fuelling growth.
Although astronomers for centuries had thought that the planetary orbits must be circular, for various important reasons, in the early seventeenth century Kepler had argued that they are in fact elliptical (although this is consistent with the idea, which became important in later contexts, that the orbits are nearly circular).
However, for practical reasons – measuring circular dichroism is easier for analysing chemical composition, optical activity is useful for photonic applications – circular dichroism has been investigated extensively in nanoplasmonic structures while optical activity has been a particular focus of studies in the microwave and terahertz frequency regimes.
According to constructivists, the vindication of reason is "avowedly circular" (O'Neill 1989, 173; Rawls 1989, 517 528).
