How is time transformed when signs appear? In the sign system of the conditioned reflex, the sign (conditioned stimulus) reverses, changes the direction of time, and overcomes its unidirectionality and irreversibility. In a sense, there is a “return” to the past in the form of the future when the sign is introduced. The sign serves as a “Time machine” of sorts. The mechanism of time transformation is possible because a mirror is embedded inside the sign, the surface of which represents (...) the psychological present time. When past experience meets that surface in the present, it may be reflected in the form of a future event. In the course of reflection, time changes its direction: if earlier time flowed from the event (the cause), it subsequently flows to other events (the purpose). Previously inaccessible past experience is now projected into the present, “comes to life” in it and is transformed into the future. In humans, unlike in animals, signs of the second order appear. Inside the signs of the second order, a mirror is built in, and the experience of the past as a subject is reflected in the future form as an object. An individual has the opportunity to consider oneself externally as an object. It goes beyond the subjective form. Thus, secondary signs once again change time direction. Due to this phenomenon, time becomes doubly reversible: first it turns around in a conditioned stimulus, and then in a secondary sign. (shrink)
