Abstract
The genesis of time is explained in the spirit of constructivism combined with the
activity approach to cognition. The cardinal temporal categories of present, past, and fu-
ture are discussed in terms of action-thoughts understood as elementary units of activity
whose structure is determined by linguistic semiosis. Husserl’s tripartite model of the
phenomenology of time (prime perception, retention, protention) is applied to the ana-
lysis of the subject’s experience of his actions. It is demonstrated that, while our lived
present is composed of the actually performed actions, our past and future are construc-
ted by reflexive action-thoughts in the cognitive domain of language. It is emphasized
that the construction of a temporal sequence that unites what is and what already or still
is not, is possible only in linguistic semiosis. The analogy with Husserl’s tripartite
structure of the time-consciousness flow helps elucidate the triad ‘present-past-future’ as
an instance of the epistemological trap of language: ‘past’ and ‘future’ are mental const-
ructs that belong to the present just as any other act of thinking.
