Memory Aids

Without memory, one could not remember logical truths about memory, truths which are inherent and thus objective and fixed even if one forgets or never discovered them.  There are things like logical axioms and other strictly necessary truths about reason itself, as well as about consciousness and introspection, which are constantly before someone even if they do not notice them, and thus they are epistemologically accessible in all situations where one is conscious.  With other things, like the precise times and dates of various events (past or upcoming) or the steps for a given procedure, a person has to remember more than what is self-evident or pertinent to logic and consciousness.  Perhaps they will struggle as individuals to store all of the relevant details within their minds.

There is not necessarily a fixed limit to what humans can memorize across different categories.  What might seem overwhelmingly complex as far as committing to memory goes can be managed even if it is only cemented in the mind portion by portion for one person or another.  It is logically possible (since it does not contradict axioms)--and there are also examples of people who have accomplished these things--to be familiar with numerous languages at once, to recall precise, miscellaneous details about Biblical and/or Quranic passages, or to, most importantly, be able to dwell on or remember a multitude of reason's abstract necessary truths on an ongoing basis.

When it comes to lesser things than philosophical truths, but things that might be of practical or professional usefulness, there is always the option of external memory aids, including transactive memory.  You remember, but you remember where you wrote information or who to consult so that you can in turn recall something else.  One can remember that one wrote a password in the notes application of one's phone, or that one can ask someone else to remind them of an upcoming doctor's appointment.  Not everyone has to remember everything themselves in this regard although it is hypothetically possible (again, it does not contradict axioms) for a person to not need to stand on environmental cues, electronic or conventional notes, or other people.

Since some of these things are very entrenched in our culture through handwritten or electronic notes/reminders, with the likes of social media notifications and cloud storage, a certain kind of person might not even attempt to lock many things within their mind.  If their mind is already occupied with things of true substance and knowability and lesser things are not memorized in order to maintain focus on the former, this is one thing.  It is another to purposefully rely as exclusively as one can on something other than one's actual memory to remind one of something.  This forfeiture of autonomy where it might otherwise be found can be a form of philosophical laziness that expresses a disregard for reality, even if specifically for the reality of human nature and memory.
