Philosophy explained simply, with visuals
Philosophy asks the questions other subjects take for granted. Do we really choose our actions, or were they fixed by everything that came before? Is it right to sacrifice one person to save five? If every plank of a ship is replaced, is it still the same ship? These questions sound abstract, but they sit underneath law, science, religion and the everyday decisions you make. Know.it's philosophy lessons use animated thought experiments to lay out each argument clearly, so you can follow it and decide what you think.
Browse free explainers on ethics (utilitarianism and the trolley problem), the philosophy of mind (consciousness and free will), schools of thought such as stoicism, existentialism and nihilism, and the tools of good reasoning — syllogisms, paradoxes, logical fallacies and Occam's razor. Comparisons like free will vs determinism set rival views side by side.
Each lesson presents the strongest version of each position rather than telling you what to believe. Ask any philosophical question and explore it in English, Hindi, Marathi, Tamil, Telugu, Hinglish and Minglish, depending on your plan and selected lesson options.
