The possibility of time travel in modern physics based on the theory of relativity has led to the study of this issue from various aspects. In this research, the metaphysical possibility of time travel will be examined and therefore its physical and technological possibility is out of the subject of this research. Metaphysical possibility is also considered to mean the compatibility of time travel with the laws of metaphysics. The metaphysical possibility of time travel is challenged by the paradoxes that arise from it. These paradoxes, despite their great diversity, fall into four general categories: Temporal Paradoxes, The paradoxes of freedom, The paradoxes of Causal, and The paradoxes of... 

In this thesis I evaluate two rival accounts: the knowledge norm of assertion and the justification norm of assertion. The former posits that “S has warrant to assert P iff S knows P”, while the latter states that “S has warrant to assert P iff S justifiedly believes (or has justification for believing) P”. I conduct this evaluation by assessing their explanatory power in two types of cases. First, I examine cases that are allegedly evidence for the knowledge norm, such as: lottery cases, Moorean cases, and challenges. In this thesis I argue that justification norm can also account for these cases. Second, I consider cases that are purported counterexamples to the knowledge norm, such as:... 

The debate over political philosophy has resurfaced five decades after the publication of John Rawls' famous book on the theory of justice. In that book, Rawls criticizes perfectionist states, And considers a state just that leaves the perfection and goodness of human beings to the citizens themselves. And the state can not be the final arbiter and interferor in the good and perfection of the citizens, and the state should never be one-sided in this conflict between the various opinions of the people about the good. Therefore, the state should only provide the means for citizens to be able to pursue their good deeds freely and equally, which is what Rawls calls the precedence of the right... 

Knowledge was traditionally understood as a one-sided foundation for all political action and, consequently, for political power. Since the late nineteenth century, however, it has been argued that political power and action also influence knowledge—and it was even suggested that power is, in fact, the sole factor shaping knowledge. Prominent advocates of this idea, such as Michel Foucault and Friedrich Nietzsche—whose thoughts profoundly influenced Foucault—employed the method of genealogy to examine historical case studies in an attempt to substantiate this claim. Yet, a critical examination of their arguments reveals that genealogy cannot support such a universal assertion. Hence, it is... 

The research examines the influence of Kant’s practical philosophy on John Rawls’ theory of justice, under the concept of “autonomy”. In the initial chapter, foundational concepts of the study such as “autonomy” and “duty” are discussed in detail within the context of prevailing views in moral philosophy, particularly deontological ethics. The overarching idea of this chapter is to establish a general conceptual framework for posing the main research question. The second chapter of this research specifically and independently elucidates Kant’s practical philosophy and clarifies his interpretation of the concept of “autonomy”. The aim of structuring this chapter is to demonstrate that... 

Black holes are theoretically significant because they are (ideal) entities fully described by just three properties: mass, charge, and spin. Their importance also stems from their unique status as spacetime entities with universal properties, including the event horizon and—when including the singularity—representing the boundary of space and time. Beyond their spacetime properties, black holes are also thermodynamic systems. Their behavior requires a theory that integrates both spacetime and thermodynamics. A black hole is something that requires both a theory of spacetime and a theory of thermodynamics to describe and explain its behavior. A consistent description of time, spacetime, and...
