emo-ammo

You could say that a lot of the things we do, they're not grounded on thought but run almost exclusively on emotions.

Trends and fashions, for example. Sometimes the trend appears rational, sometimes not, but when a trend blows up and gets adopted by the masses, you can be sure that its success owes a lot to emotions: to fit in with peers, to be seen as a trend-setter, etc; these feelings act as influential motivators.

For people with agendas to push, to be vulcan, that is to act exclusively on intellect and rationality, is to behave in a manner alien to the people of earth.

As the cliche goes, you cannot force someone to love you, so you attempt persuasion. To love something, is to have a feeling inside of you, burning from your core across your entire being, is very different from knowing the benefits and advantages of an action.

In other words, it is not something you can debate with your mind and superior intellect, but instead is something that needs to be inspired, either by an act, or speech, or presence.

And when the audience has strong inertia away from your intended outcome, you would need a clear ringing stimulus if you were to have the slightest chance of getting your preferred responses.
