“…This was the case in Lewin's "Kriegslandschaft", his programmatic work published in 1917, in which he showed that, while marching on a field, the soldier will look at the field differently in times of peace than in times of war (Bäumler, 2017;Keller, 2016;Previšić, 2016;Wieser, 2014). Starting from this idea, Lewin advanced his theory claiming that a field exists in a state of quasi-stationary equilibrium: it is neutral when there are no forces acting upon it or when the acting forces annihilate themselves (Autissier et al, 2018;Rouchy, 2009;Stützle-Hebel, Antons, 2017;Talpin, 2017). However, this neutrality is rarely met in real life, when driving forces and restraining forces impact upon a certain situation (Damian, Susanu, 2018;Watkins, Lundberg, 1998).…”
