Comparison between the relation of the self and the other in Descartes and Pascal’s thought

While Descartes tried in his philosophy after using the procedure of doubt by introspection and rational intuition to achieve the essence of “the self” as thinking substance and then by clear and distinct ideas that he already had of “the other” (including God and other creatures) to make judgement about the existence and the essence of “the other” and in the end by using the truths which were known with the mediation of natural light of reason to acquire the regulator moral principles with “the other”, Pascal in addition of asserting the impossibility of discovering “the self” by introspection, reversed all the creative process of Descartes and considered discovering of “the self” in its relation with “the other” and succedent to it and as a result, the free thinking and autonomous Cartesian subject that faced “the other” only as its object of knowledge and supposed the existence and the essence of “the other” as something dependent on the ideas that he had from them, manifested in complete contrast with the heteronymous and subordinate Pascalian human that his only alteration before and after grasping the God’s grace lies in experiencing the different kinds of heteronomy and the impossibility of autonomy and finally, regulation of relation with “the other” just establishes by referring to a “super other” i.eh. God.
