On the Relationship between Truth and Liberal Politics
This paper examines the relationship between truth and liberal politics via the work of Bernard Williams and Richard Rorty. I argue that Williams is right to think that there are positive relations between truth, specifically a realist understanding of truth, and liberal politics that Rorty's abandonment of the realist vocabulary of truth undermines. At the heart of this concern is the worry that abandoning the realist vocabulary opens up the possibility that the standards of justification for our true beliefs can be manipulated by those with the power to do so in order to further their own political ends. The political benefit of realism is that it fixes the standards of justification and makes them immune to manipulation by the use of power. However, I suggest that there is a form of realism available that Rorty can accept which would deliver the political benefits of the realist vocabulary without requiring him to accept the thick realist metaphysics that he wants to avoid. My conclusion is that there is a positive and important relationship between truth and liberal politics, a relationship that can be sustained without any necessary commitment to realist metaphysics.
Truth, politics, and self-deception
L'A. s'interroge sur la place de la verite et sur les mecanismes de la communication, de la transmission de ce qui est tenu pour vrai dans le domaine de la politique. Il s'efforce d'identifier les beneficiaires des informations politiques qualifiees de vraies et met en exergue un certain nombre de mecanismes d'aveuglement. Il montre que le discours politique au sein des medias oscille, de nos jours, entre divertissement et transmission d'informations vraies
VLA stereoscopy of solar active regions. 2: Altitude, relative motion, and center-to-limb darkening of 20 centimeter emission
A newly developed method of stereoscopic correlation is applied to solar radio maps at a wavelength of 20 cm. On the basis of stereoscopic correlations between radio maps obtained on 6 different days we establish the presence of 66 radio source components associated with 22 active regions. We find the following statistical results for active region source structures at 20 cm: 1. The observed lifetime is consistent with an exponential distribution having an e-folding time scale of greater than 18 days. 2. The average altitude of 20 cm sources is 25 +/- 15 Mm; 90% of the sources are found in heights less than 40 Mm. 3. The average diameter of discrete source structures is 48 +/- 15 Mm, implying a vertical/horizontal aspect ratio of q(sub A) approx. = 0.5. 4. No significant source motion has been found with respect to the standard differential rotation rate of Omega = 13.45 deg - ((3 deg (sin(exp 2)B)). 5. We find a statistical limb darkening, which can be described by the relation (T(sub B)(alpha))/T(sub B)(0)) = 0.4 + ((0.6(cos(exp 2) alpha)) for sources with T(sub B) greater than 0.5 MK. 6. The degree of source polarization is 15% +/- 10% and is independent of source location. 7. Bright sources (greater than or approximately equal to 0.5 MK), or equivalently, long-lived sources (greater than or approximately equal to 5 days) show a systematic variation of their altitude as function of the center-limb distance.
