Liberty in key works of John Locke and John Stuart Mill

The ideas of liberty presented in the important works of John Locke and John Stuart Mill, The Second Treatise of Government (1689) and On Liberty (1859), are often viewed as belonging to the same conceptual tradition, that of English liberalism. This thesis is an articulation of the diversity between the theories of liberty expressed by Locke and Mill in the Second Treatise and On liberty. \ am aiming to provide a corrective to the tendency to ignore or to gloss over very significant differences between the two men. The work concentrates on the philosophical aspects of each theory of liberty, arguing that they differ in four respects. These are; definitions of liberty; justifications of liberty; how much liberty and for whom they recommend it, and finally, who they believe threatens liberty and how this threat is to be curbed. It is the purpose of this thesis to show that in terms of these areas Locke and Mill are pursuing different ends. I conclude that Locke and Mill present strikingly different theories of liberty and cannot be thought of as belonging to the one conceptual tradition in terms of the definition, the justification, the prescription and the threat to liberty. Ultimately, I question the value of including Locke and Mill in the one conceptual tradition of liberty solely on the basis that they argue ‘freedom from.’

Misunderstanding John Stuart Mill on science: Paul Feyerabend`s bad influence

Feyerabend, 1975; Feyerabend, 1981 and Feyerabend, 1987 takes J. S. Mill’s On Liberty to support the proliferation of theories in science and to emphasize the fallibility of scientific knowledge. On Liberty, according to Feyerabend, contradicts and overthrows Mill’s major study of science, A System of Logic. Staley (1999) reads the 2 works of Mill as giving complementary accounts of science. The present author rejects these interpretations of Mill, arguing that A System of Logic and On Liberty are mutually compatible since On Liberty concerns the nature of non-scientific knowledge and the methods that Mill believes are appropriate to expanding and assessing that knowledge.

Liberalism and economic growth: a theoretical exploration

This article explores how the liberal tradition of political thought has dealt with the prospect of limits to economic growth and how it should approach this issue in the future. Using Andrew Moravcsik’s explanatory liberal theory, it finds that the commitment of governments to growth stems primarily from the aggregation of societal preferences for the social goods that growth produces. The arguments of liberal thinkers who have grappled with the issue of growth are then examined to gain a deeper theoretical understanding of the relationship between liberal democracy and growth. These include John Stuart Mill, for whom a non-growing economy was essential for overcoming the tension between liberty and equality; Ronald Dworkin who argues that growth is a derivative means to further more fundamental ends; and Marcel Wissenburg who suggests that it is legitimate for liberal democracies to limit the preference for growth if it risks undermining liberal norms and institutions. Using
these theoretical insights, it is argued that environmental degradation, which is partly driven by growth, now threatens the fundamental liberal commitments of many liberals, including some forms of
state neutralism, utilitarianism, inalienable individual rights and above all human autonomy. Therefore, liberal democratic states not only can, but must move towards a post-growth economy to secure these objectives into the future.

Euthanasia and assisted suicide : a liberal approach versus the traditional moral view

Within the context of the debate over the recent suspended sentence given to John Stuart Godfrey by Underwood J in the Supreme Court of Tasmania for assisting his elderly mother with her suicide, this article examines some of the more popular arguments for and against the moral acceptability of euthanasia and assisted suicide. This article considers the arguments put forward on the “difference principle” by Rachels and Nesbitt before critically examining the liberal approach to the euthanasia issue as proposed by Kuhse. It is argued that whilst Kuhse is correct to reject the difference principle, she does so for the wrong reasons. The penultimate section of the article provides an overview of the traditional moral view against killing. The final part assesses whether the arguments put forward by proponents of the liberal approach are capable of overcoming this view.

Functional morphology of the gastric mills of carnivorous, omnivorous, and herbivorous land crabs

Terrestrial decapods consume a wide variety of plant and animal material. The potential adaptations of carnivorous, omnivorous, and herbivorous terrestrial crustaceans were studied by examining the functional morphology of the gastric mill. Two closely related species from each feeding preference group were examined to identify which features of the mill were due to phylogeny and which were due to adaptation. The morphology of the gastric mill matched the diet well; the gastric mills of the carnivorous species (Geograpsus grayi and Geograpsus crinipes) possessed a blunt, rounded medial tooth and flattened lateral teeth with a longitudinal grinding groove. These features make them well suited to a carnivorous diet of soft animal tissue as well as hard material, such as arthropod exoskeleton. In contrast, the mill of the herbivorous gecarcinids (Gecarcoidea natalis and Discoplax hirtipes) consisted of a medial tooth with sharp transverse ridges and lateral teeth with sharp interlocking cusps and ridges and no grinding surface. These features would efficiently shred fibrous plant material. The morphology of the mill of the omnivorous coenobitids (Coenobita perlatus and Birgus latro) was more generalized toward a mixed diet. However, the mill of B. latro was more adapted to deal with highly nutritious food items, such as nuts and heavily calcified decapods. Its mill possessed lateral teeth with extended ridges, which sat close to the calcified cardiopyloric valve to form a flattened floor. Hard items trapped in the mill would be crushed against this surface by the medial tooth.

Improving the prediction of the roll separating force in a hot steel finishing mill

This paper focuses on the development of a hybrid phenomenological/inductive model to improve the current physical setup force model on a five stand industrial hot strip finishing mill. We approached the problem from two directions. In the first approach, the starting point was the output of the current setup force model. A feedforward multilayer perceptron (MLP) model was then used to estimate the true roll separating force using some other available variables as additional inputs to the model.

It was found that it is possible to significantly improve the estimation of a roll separating force from 5.3% error on average with the current setup model to 2.5% error on average with the hybrid model. The corresponding improvements for the first coils are from 7.5% with the current model to 3.8% with the hybrid model. This was achieved by inclusion, in addition to each stand's force from the current model, the contributions from setup forces from the other stands, as well as the contributions from a limited set of additional variables such as: a) aim width; b) setup thickness; c) setup temperature; and d) measured force from the previous coil.

In the second approach, we investigated the correlation between the large errors in the current model and input parameters of the model. The data set was split into two subsets, one representing the "normal" level of error between the current model and the measured force value, while the other set contained the coils with a "large" level of error. Additional set of data with changes in each coil's inputs from the previous coil's inputs was created to investigate the dependency on the previous coil.

The data sets were then analyzed using a C4.5 decision tree. The main findings were that the level of the speed vernier variable is highly correlated with the large errors in the current setup model. Specifically, a high positive speed vernier value often correlated to a large error. Secondly, it has been found that large changes to the model flow stress values between coils are correlated frequently with larger errors in the current setup force model.
