When we take permanent notes, it is much more a form of thinking within the medium of writing and in dialogue with the already existing notes within the slip-box than a protocol of preconceived ideas. Any thought of a certain complexity requires writing. Coherent arguments require the language to be fixed, and only if something is written down is it fixed enough to be discussed independently from the author. The brain alone is too eager to make us feel good – even if it is by politely ignoring inconsistencies in our thinking. Only in the written form can an argument be looked at with a certain distance – literally. We need this distance to think about an argument – otherwise the argument itself would occupy the very mental resources we need for scrutinizing it.
