DEMORALIZED PEOPLE CANNOT BE RATIONAL

a) Demos implies "people" aka collectivization of natural units into artificial groups. Within such a group of people (demos) one rationalizes US vs THEM.

b) De-moral aka division of moral implies a further division of rationalization (conflict of reason). A moral people rationalize in-between good vs bad, which demoralization further divides into for example pure goodness vs utter evil. It's still the same conflict, yet with added mental layers to obscure the living being.

easily influenced by advertising

Easily (ones perception) influenced (all perceivable) by advertising (suggestions by another).

It's easy for ones perception to be turned against (ad vert) others...consent given implies offense taken.

susceptible to hypnosis. Why would that be?

Because consenting to suggestion puts ones perception (nosis) to sleep (hypno).

good information...

...implies ones rationalization (good vs bad) of suggested information (operation), while ignoring perceivable inspiration (psyche).

Psyche (animating power) moves through one, hence all perceivable moving through each ones perception, while holding onto suggested implies opera - "effort".

Rationalization/reasoning over information wastes effort (exertion)...adaptation to inspiration affords aka puts forth being (re-animation).
