Beliefs are ideas that one thinks are true. All actions one chooses to do are justified by their beliefs, and certainty ensures that the correct actions are taken because the beliefs that justified them are confirmed to be true or false. Therefore, certainty should be attained to know what to act. Knowledge about reality comes from the combination of evidence of the senses with inductive reasoning. However, inductive reasoning doesn't result in certainty because there may always be missing variables. This means that one should act according to what results in the experiences that help us know the probability of a belief being true by having considered more variables.

However, variables may be lost given that there's imperfect memory which means that it's necessary to create a device that can perfectly imagine past experiences. To show the true nature of reality, ultimately answering questions like what one ought to do: one's experiences should be added to a map of reality that orders events in chronological order. This map can then be used as a visual aid that one can use to inductively reason and predict the cause and effect of every event.

Belief → Action → Experience → Imagination → Reason → Knowledge → (back to) Belief
[I'd use a device to aid with recreation of past experiences and a map to attach my reasoning to so that no variables are lost]
