We live a complex life of time, sometimes in the past (Then), sometimes in the future (Soon) , and little time in the desirable present time (Now). Examining the ways our human brain uses our past(s) in guiding present time, we recognize time as the principle perceiver of our perceptions. Clock time and developmental time lead to stages of time usage including how we relate to others using time i.e. past timing (bs) , activities (work) and negative perceptional projections: anxieties and fears. If time permits, we will deal further with the time principles of perception.
