Common sense

Descares asked, “On what basis can I be sure that everything I see is not the product of a demon that I can only see. If the stick inserted in the water seems curved, how can I be sure of everything.” Descares reasons: “There is only one thing that cannot be challenged – that I think.” And then, “But how can I be sure I really exist?”

Descares replies: “The fact that I exist cannot be an delusion, for God would not be God if he cheated on me. So: what is certain is that I think, and it follows in a certain way that I exist: therefore COGITO ERGO SUM”. John Lock criticized Descartes more or less like this: “In order to convince himself of the truthfulness of things OBVIOUS TO COMMON SENSE, Descartes first denies common sense, and then – to justify what he has denied – refers to the idea of a good god, which I go much harder to prove than the OBVIOUS fact that the world is not delusional. It’s like putting something in your right pocket with your left hand that’s already there.”

In polish lessons, everyone stood up and explained how he understood the phrase: “Cogito ergo sum”. Everyone explained something like this: “If I have the ability to think, I am a human (in my guess – not a monkey). Someone on LI wrote: “BREXIT is A BIG LOSS FOR EU LAW.”
