Universal Basic Income has become a popular idea in the last few decades even though one can find its roots in the earlier centuries. In this thesis, I have examined the position of UBI in the works of the most influential contemporary philosophers. By connecting the idea of UBI with some certain concepts from different philosophers, I aimed to improve the overall understanding of UBI. I have mentioned the concepts such as "labor", "leisure", "idleness", "boredom", "poverty", "inequality", "distribution", "happiness", "power", (...) "needs", "truth", "alienation", etc. I have used a literature methodology for my research. I have tried to read and relate the concept of UBI with the works of 10 philosophers: Arthur Schopenhauer, Karl Marx, William James, Bertrand Russell, Michel Foucault, John Rawls, Robert Nozick, Noam Chomsky, Slavoj Zizek, Peter Singer.
