Viewed in general terms:
Because man has memory, he thus feels the presence of “the past,” “the present,” and “the future”; or, in more precise terms, he feels that “the past condition,” “the present condition,” and “the future condition” is present.
Viewed in specific terms:
Because “the past condition” leaves its “traces” as memory, man feels the presence of “the past;” or, in more precise terms, he feels the presence of “the past condition.”
Because the human memory records the alternation of day and night as a matter of routine, he assumes that “the future” or “the future condition” that he will go through is present.
Because man’s body is made up of matter, which is “always present” in this universe, he thus feels(with his “feeling of existence”) that he is “always present” or “always at the present time.” In more precise terms, he feels that he is “always in the present condition” till the end of his life. All his life man feels that he is “always present,” experiencing a variety of conditions sequentially, yet with each sequence of his experiences always in “the present condition.” In other words, because he is “always present,” he feels that he is consistently at “the present time” and in “the always changing present condition.” He is never in “the past condition.” It is only through his memory that he assumes that all those conditions that he has experienced do exist.
Obviously, what men have all this time claimed to be “the past” or, to be exact, “the past condition” is just non-existent! What really is going on is that the basic matter that forms “the past condition” has now changed its configuration to form “the present condition.”
Man, who is destined to have memory, will continue to adopt the third concept of time, which is necessary for him in his attempt to observe both his very self and the universe. It is for this very reason that the whole content of this universe is said to be constantly undergoing “a change from one condition to another.”
That our brains keep receiving the various impressions of “the past condition” stored in them as memory, despite the fact that there is no such thing as “the past condition,” gives us reason enough to conclude, from a negative standpoint, that “Memory is deceptive.”
Since the day human beings came into existence and also since the day he was born on earth, man with the memory he possesses has always had the feeling that “the past” or the “past condition” does exist, although in fact neither “the past” nor “the past condition” is what it appears to be in this universe. That is why the writer has entitle this book “The Deceptive Nature of Memory.”
