Lived choice is a concept that has been proposed by the author. Lived choice, in opposition to the choice as an act, is not an act but an experience or an event. As for lived choice of fascination, it is an experience of being fascinated by something. Such experience is, as it were, disarmament of oneself against that something. The person who has such experience has a special connection with that something in that the person disarms solely against that something. In that sense the person can be said to have chosen unintentionally that something. This choice is that which is lived. That is why such choice is called here lived choice. The purpose of this paper is to make clear the theoretical background of the concept, and to explore its theoretical significance, and finally to propose another type of lived choice, i.e. lived choice of société ouverte.
