Concept of Truth is the most fundamental concept in any intellectual activity. Knowledge systems are distinguished, above all, by their different viewpoint about truth and different criteria which they present for determining truth. Phenomenology, that its motto is returning to things as such, should introduce a definition of truth free from the presuppositions which lie in the definitions (implied or expressed ones) of it in most knowledge systems. In this project, we try to clarify concept of truth as correlation of transcendental act in philosophy of Husserl, and also study antecedents and consequents of this conception. In this project we investigate the place of the idea of “truth” in... 

This thesis is going to investigate the ontological foundation of Science and Tool. To this aim, it refers to Heidegger’s works especially the Being and time. Heidegger gets involve in analyzing Science in the Being and Time. He emphasizes on importance of establishment of a fundamental knowledge which should ontologically recognize basic concepts and methods of Sciences, to cause a real progress in sciences. Heidegger also asserts that the Mathematical interpretation of the world is not a fundamental, and it must be replaced with phenomenological interpretation, which clarifies the ontological foundation of the theoretical view, and regards to all aspects of world’s existence. In this... 

In this research, first of all, the main question of Heidegger and his epoch is investigated. If we read Heidegger along the tradition of German philosophy, then it is perceived that the problem of science is the most central subject matter standing against Heidegger. My question is this: how Heidegger reaches to this existential phenomenological view about science. Regarding that, by giving a coherent narration about a crucial problem called 'the crisis of science', in the first chapter I gave a short view to philosophies preceding Heidegger, some important of which is Dilthey's philosophy of life, phenomenology of Husserl, and south-west school of neo-Kantianism. The second chapter... 

In this work, we establish the constancy of expansion ratio (density factor) and adiabatic flame temperature for predicting lower explosive limits and further establish the constancy of expansion ratio for measuring upper explosion limits. Flammability limits are important characteristics of combustion processes. The flame can only propagate in a specific range of ratios of concentration of fuel to oxidant. The maximum of this concentration ratio that make possible propagation of flame in a mixture, is called upper flammability limit. The minimum of this ratio that make flame propagation possible is called lower flammability limit. Limits of flammability change with initial conditions such... 

How is it possible for mind to be directed to the world? Or for it to be opened to the world? This question – formulated as the problem of knowledge - has been the central question of the modern philosophy. Rediscovering of the concept of "intentionality" as the mark of the mental by Franz Brentano, Contemporary philosophy succeeded in addressing this central question in a more direct and explicit a way. Intentional character of mind is more obvious in sensory experiences. Perception seems to be the minds openness to the world. But the possibility of having illusory or hallucinatory experiences challenges that very conception of perceptual experiences as openness. In analytic philosophy... 

The role of Technological Human Body is mainly overlooked in the Philosophy of Technology. However as result of diverse bodily technologies (somatechnologies) which are emergent everyday, for either enhancement, rehabilitation, or even recreational activities, the realtion between bodies and technologies are such entangled that no longer could anybody ignor it. Cyborg is an amalgamation of Human and Machine. The philosophical challenges that such an entity brings forth is immense; Agency, Intentionality, Subjectivity, Power relations, Ethics to mention but a few. In this study we try to investigate such issues through a phenomenological and feminist stance by examining Everyday cyborgs, i.e....
