D is for


In his Meditations Renee Descartes famously sets out to find a trustworthy ground for knowledge. That is he is looking for the certain, the indubitable and (of course) sets out to find it by trying to doubt everything and begin anew, counting only on what cannot be doubted. In 1637 he formulated that in French: je pense, donc je suis, a few years later he’d say it in latin with his famous Cogito ergo sum (usually translated: “I think therefore I am”). Just shy of 300 years later Husserl would provide a more intentional version saying: Ego cogito cogitatum (I think thoughts).
