The Problems of Philosophy is book written by Bertrand Russell in 1912. In this book, RusselL, who is considered as a premier 20th Century logicians, attempts to make a brief and accessible guide to the problems of philosophy that appeals to practitioners, students, and even the general public. He focus on problems that he believes will arouse positive and productive discussions. He maintains his focus in the philosophy of knowledge rather than metaphysics: “If it is uncertain that external objects exist, how can we then have knowledge of them but by probability. There is no reason to doubt the existence of external objects simply because of sense data.”
Russell highlights important theories of Plato, Aristotle, René Descartes, David Hume, John Locke, Immanuel Kant, Georg Wilhelm Friedrich Hegel, among others to establish the basic ideas for philosophical inquiry by the reading public. He also guides the readers through his own famous 1910 theories on "knowledge by acquaintance and knowledge by description", effectively creating one of the foremost introductions to philosophy.
