Symbolic Logic Symbolic logic is the method of representing logical expressions through the use of symbols and variables, rather than in ordinary language. This has the benefit of removing the ambiguity that normally accompanies ordinary languages, such as English, and allows easier operation. There are many systems of symbolic logic, such as classical propositional logic, first-order logic and modal logic. Why do we believe in electrons, but not in fairies? by Benjamin Kuipers No one has directly observed either electrons or fairies.

Existentialism, Sartre’s The philosophical career of Jean Paul Sartre (1905-1980) focuses, in its first phase, upon the construction of a philosophy of existence known as existentialism. Sartre's early works are characterized by a development of classic phenomenology, but his reflection diverges from Husserl’s on methodology, the conception of the self, and an interest in ethics. These points of divergence are the cornerstones of Sartre’s existential phenomenology, whose purpose is to understand human existence rather than the world as such. To sleep less and dream more If for a moment God were to forget that I am a rag doll and granted me a piece of life, I probably wouldn't say everything that I think; rather, I would think about everything that I say. I would value things, not for their worth but for what they mean. I would sleep less, dream more, understanding that for each minute we close our eyes, we lose sixty seconds of light.
