2. The Trick of Time
We have already seen how the Mind employs a neat trick to put all the experiences in an easily accessible sequence. It uses an axis called time and marks the events on it. Experiences happen, they don’t come with a time stamp attached to them, the Mind adds the stamp. It makes the experiences more organized and their recall (simulation via impressions) easier. Whenever there is a change, there is an experience, or we can as well define an experience as Change (which we have already done, see Experiencing). So change is more fundamental. Some changes happen at seemingly regular fashion, such as change of a day into night, orbit of the earth around the Sun and vibrations of atoms. This allows us to compare an irregular change with regular one, and we can express the irregular change in terms of regular one. Thus the Physical Time is born, which is just a regular change, it is not an entity, as it does not exists as such, its merely a concept. We use devices, clocks, to count the regular changes. Comparing an irregular experience with the counts of a clock immediately gives more information about the change, and the concepts of slow or fast are created. Now we can stamp a number on an event, making it even more structured. Physical time is derived from physical changes that happen around us, but there is another time – the Subjective Time, which is based on mental changes, and has no correspondence with physical one [3].
