Reduction is a concept first introduced by Descartes in explaining his view of the rationalization of philosophy through mathematics. He seeks to consider length, breadth, and depth for phenomena so that reducing the phenomenon to his own analytical geometric apparatus; thus shrinking the whole world into a small machine. In the present study, the authors took into account the deficiency in defining the reduction of phenomena to a mathematically sound system as the reason for a large group of problems and therefore they came to redefine the Cartesian reductionism of phenomena by removing the search space through a learning system. In due definition, it is possible to reduce the NP problems to P space without using a quantum algorithm that requires a quantum computer to exist. The present study points out that the problems arising from the mathematical modeling of the Covid-19 pandemic are due to a deficiency in the definition of Cartesian reduction, which leads to an increase in the computational complexity of its diagnosis and treatment using computational tools.

Philosophers consider sense as a means for true cognition. In spite of the fact that Islamic philosophy are generally regarded as rational philosophy, it does not mean that they do not assume epistemological value for sense. To some of them, including Ibn Sina, sense is extremely important. In the present article, I argue that the role of sense in Ibn Sina's epistemological system is very significant although the I would not consider Ibn Sina  as an empiricist in the sense that Hume is in the Western philosophy. Rather, I consider Ibn Sina empiricism similar to  the theory of Locke. It is due to the fact that Ibn Sina considers the human mind as a tabula rasa with no actual data at the birth. It is believed that with sense the knowledge begins. In addition, in this study, by taking into the account of both empirical and rational criteria (in Ibn Sina's epistemological system), it is ultimately accentuated that in the most cases, Ibn Sina's tendency is found to be more toward empiricism. In another part of the paper, the role of sense in the realm of the concepts and affirmation (sensory and rational) is explained. It is concluded that sensory conceptions are the outcomes of sense. Other ideas (concepts) are mediated by sense; sensory affirmations immediately come from sense and in rational affirmations, sense plays a role as an introduction. In sum, this is the explanation of Ibn Sina's statement: "Whoever has no sense will have no knowledge"

The relation of causal necessity with free will has been a source of great debate in the history of philosophy and theology. However, in recent years, it has also been discussed in the science of Usul al-Fiqh. After explaining the compatibility of causal necessity with free will, Ākhūnd Khurāsānī speaks of the 'shattering of his pen.' Two interpretations have been given for this statement. Muḥaqqiq Iṣfahānī considers the theory of compatibility that Khurāsānī presented as being correct. However, he interprets the 'shattering of the pen' to be a reference to another matter, i.e., the problem of the recompense of an agent in the case where causal necessity is accepted. His explanation of the aforementioned compatibility and the permissibility of the recompense of sinners has been evaluated in this article. On the contrary, Muḥaqqiq Na'ini considers the 'shattering of the pen' to be a reference to the problem of the conflict between causal necessity and free will. He says that aside from the popular preliminaries of free will, such as knowledge and intention (which are the products of causal necessity), there is a need for something that he calls 'talab'-a noetic action that stems from the governance of the soul. He considers this talab to fall outside the scope of causal necessity. This paper seeks to examine the views of these two illustrious students of Ākhūnd Khurāsānī so that the various Usuli dimensions of this discussion can be clarified.
