L’évolution de l’argument contre l’idéalisme dans la Critique de la raison pure

Chacune des éditions de la Critique de la raison pure contient une preuve de la réalité du monde externe : la première se trouve dans le « quatrième paralogisme » et la deuxième dans la « Réfutation de l’idéalisme ». Ce travail examine l’évolution du premier argument vers le deuxième, en rendant compte de deux critiques importantes de la première édition qui ont influencé le second travail de Kant. La deuxième partie de ce travail se concentre sur des problèmes propres à la Réfutation, où sont traités des sujets particulièrement problématiques, tel que la structure de la conscience empirique déterminée, le rôle du permanent dans l’établissement de l’objectivité, ainsi qu’un argument secondaire présenté dans les notes de bas de page du texte principal et de la préface.

Securing Tenure for Sustainable Livelihoods: A Case of Women Land Ownership in Anglophone Cameroon

The majority of women in Third World countries depend on land for their livelihood. Security of tenure is important for them to ensure sustainable development, especially in rural areas. In most parts of Africa, land ownership is affected by traditional values, inheritance rights, and government influence. These forces have provided varying types of tenure which are detrimental to the women in rural and urban areas. Land acquisition and its development has been an emotive issue due to traditional pressures and the law as regards the process of land certification. The government and traditional administrations are highly involved in the way women own land and subsequently develop it in Anglophone Cameroon. State authority over land acquisition is important, but the process for obtaining land title is herculean especially for the rural woman. This study illustrates that land acquisition and development by women constitute a problem because of traditional pressures and the law guiding the process of land certification. There is need to exhume the barriers of government’s legal instrument (The Land Consultative Board) that regulates the ownership of land and to revisit some traditional practices as regards land ownership that impact negatively on women in a changing and globalizing world. A compromise approach is advocated for land acquisition that can transcend traditional barriers as well as render the process of land registration more realistic especially for women.

La chose en soi comme concept «critique» : le problème de la limitation de la connaissance dans la Critique de la raison pure de Kant

Dans ce mémoire, nous nous proposons de montrer que le concept kantien de chose en soi est à la fois un concept métaphysique et un concept critique. En ce sens, la chose en soi doit être comprise comme un objet transcendantal réel qui existe à titre de cause des phénomènes. Si, contrairement à ce que soutenaient F.H. Jacobi (1787) et G.E. Schulze (1791), cela ne suppose pas de sortir du criticisme, c'est qu'une telle affirmation prend la forme d'une connaissance analogique qui respecte les limites de la connaissance humaine. De fait, la connaissance analogique permet de pointer en direction de quelque chose dont la nature (Beschaffenheit) peut demeurer problématique, tout en permettant d'affirmer son existence (Dasein). Nous serons dès lors conduite à montrer que la Critique de la raison pure fournit bel et bien les outils nécessaires permettant de rendre compte de l’existence des choses en soi à titre de causes des phénomènes.

Sur l'interprétation Heideggérienne du chapitre "Du schématisme des concepts purs de l'entendement" de la critique de la raison pure de Kant

Cette analyse porte sur le schématisme des concepts purs de l’entendement, tel que présenté par Emmanuel Kant dans la Critique de la raison pure et interprété par Martin Heidegger. La lecture proposée par Heidegger est critiquée par un bon nombre de commentateurs dans la mesure où ils considèrent que son interprétation ne lui sert qu’à faire valoir ses propres théories philosophiques au sujet du Dasein et de l’ontologie fondamentale. Notre approche se distingue de la leur dans la mesure où nous tentons de comprendre les raisons qui ont poussé Heidegger à défendre l’interprétation du schématisme qui est la sienne. Notre étude s’attarde au texte de Kant de manière à en souligner les éléments qui ont permis à Heidegger d’établir sa lecture, telle qu’il la présente dans son ouvrage de 1929, ayant pour titre Kant et le problème de la métaphysique. La méthode utilisée est comparative, car notre but est de démontrer la valeur de l’interprétation heideggérienne contre celle des commentateurs qui le critiquent pour des raisons insuffisantes. Bref, le thème du schématisme kantien est analysé de long en large et la conclusion à laquelle nous parvenons est que Heidegger a permis des avancées philosophiques considérables par son herméneutique de la Critique et qu’il est nécessaire de leur accorder l’attention qui leur est due.

L’analogie juridique dans la Critique de la raison pure

La Critique de la raison pure est traversée de part en part par une analogie juridique dont l’étude peut enrichir la compréhension de l’œuvre. Il est ainsi question, dès la préface, d’une raison qui se juge elle-même devant son propre tribunal, ce qui constituera le point de départ de notre analyse. Or, ce tribunal très particulier doit se fonder sur une connaissance de soi approfondie de la raison. Cette entreprise est de fait réalisée au fil des développements de la Critique. Le rôle bien particulier joué à cet égard par les trois déductions présentes dans l’œuvre sera dûment examiné. On verra par ailleurs que la déduction doit elle-même être considérée plutôt comme procédure d’inspiration juridique que comme inférence, tout en conservant pourtant un statut de preuve philosophique. Les nombreuses allusions juridiques effectuées par Kant au fil de l’œuvre seront ainsi mises à profit dans le cadre de cette interprétation.

Dynamics of Land Use in Recently Settled Forest Areas: a Case Study of Attappady , Kerala

The present study on the dynamics of land use in recently settled forest areas. In the course of events, tribals lost their land; the demographic structure of Attappady changed; the cropping pattern got diversified; traditional techniques of production were ruined; new crops and new techniques of cultivation came to stay; and the entire cost and return structure of production underwent radical change. Migration to Attappady is essentially a continuation of the Malabar migration process from Travancore, through, some people from Tamil Nadu also had migrated to this region earlier. The demographic structure, along with land structure, has changed in favour of the settlers within a short span of time. Lack of security of ownership has acted as a strong reason for wanton exploitation of land resources. The major influencing factors on crop choices among settlers were labour endowment, date of settlement and education. Attappady is an unique ecosystem in Kerala characterized by many interdependables. The latest hand of environmental degradation is a grave danger especially on sloppy terrains,which are under cultivation of tapioca and dry annual crops like groundnuts, cotton, grams etc. Soil erosion as a result of the unplanned cultivation of these crops has resulted in dramatic decline in soil fertility and hence low crop productivity. This calls for a watershed management approach for the sustainable development of the region. A progressive agrarian transformation is warranted to maintain the homegarden as a sustainable production system in ecological and socio-economic terms.

Land Transfers and Peasant Mobility

It is hoped that the present study by analysing the dynamics of agrarian change and peasant mobility may contribute to the on-going debate on this issue in India and other developing countries. It may also help to throw light on the validity of some of the theories formulated on the basis of experience in different regions and at different times. The study is likely to be of special importance as it covers an area which has one of the highest densities of population. The area has also witnessed sweeping changes in agrarian structure as a result of the most radical land reforms among the Indian states.

Studies on the Quality of Rainwater at Various Land Use Locations and Variations by Interaction with Domestic Rainwater Harvesting Systems

The present study focused on the quality of rainwater at various land use locations and its variations on interaction with various domestic rainwater harvesting systems.Sampling sites were selected based upon the land use pattern of the locations and were classified as rural, urban, industrial and sub urban. Rainwater samples were collected from the south west monsoon of May 2007 to north east monsoon of October 2008, from four sampling sites namely Kothamangalam, Emakulam, Eloor and Kalamassery, in Ernakulam district of the State of Kerala, which characterized typical rural, urban, industrial and suburban locations respectively. Rain water samples at various stages of harvesting were also collected. The samples were analyzed according to standard procedures and their physico-chemical and microbiological parameters were determined. The variations of the chemical composition of the rainwater collected were studied using statistical methods. It was observed that 17.5%, 30%, 45.8% and 12.1% of rainwater samples collected at rural, urban, industrial and suburban locations respectively had pH less than 5.6, which is considered as the pH of cloud water at equilibrium with atmospheric CO,.Nearly 46% of the rainwater samples were in acidic range in the industrial location while it was only 17% in the rural location. Multivariate statistical analysls was done using Principal Component Analysis, and the sources that inf1uence the composition of rainwater at each locations were identified .which clearly indicated that the quality of rain water is site specific and represents the atmospheric characteristics of the free fall The quality of harvested rainwater showed significant variations at different stages of harvesting due to deposition of dust from the roof catchment surface, leaching of cement constituents etc. Except the micro biological quality, the harvested rainwater satisfied the Indian Standard guide lines for drinking water. Studies conducted on the leaching of cement constituents in water concluded that tanks made with ordinary portland cement and portland pozzolana cement could be safely used for storage of rain water.

Electrical conductivity, dielectric constant and phase transitions in pure and doped diammonium hydrogen phosphate

DC and AC electrical conductivity measurements in single crystals of diammonium hydrogen phosphate along the c axis show anomalous variations at 174, 246 and 416 K. The low-frequency dielectric constant also exhibits peaks exactly at these temperatures with a thermal hysteresis of 13 degrees C for the peak at 416 K. These specific features of the electrical properties are in agreement with earlier NMR second-moment data and can be identified with three distinct phase transitions that occur in the crystal. The electrical conductivity values have been found to increase linearly with impurity concentration in specimens doped with a specific amount of SO42- ions. The mechanisms of the phase transition and of the electrical conduction process are discussed in detail.

High‐temperature phase transitions in pure and deuterated ammonium dihydrogen phosphate: Conductivity and dielectric measurements

Results of axiswise measurements of the electrical conductivity (dc and ac) and dielectric constant of NH4H2PO4 confirm the occurrence of the recently suggested high‐temperature phase transition in this crystal (at 133 °C). The corresponding transition in ND4D2PO4 observed here for the first time takes place at 141.5 °C. The mechanism involved in these transitions and those associated with the electrical conduction and dielectric anomalies are explained on the basis of the motional effects of the ammonium ions in these crystals. Conductivity values for deuterated crystals give direct evidence for the predominance of protonic conduction throughout the entire range of temperatures studied (30–260 °C).
