A mistake about Tomist thinking could have let...

ST. Tomas was one of most thinkers of scolastic sciences around to many topics.

Every body knowed him by one of their writings most famous is Suma Theological the one where him discovered his investigationes about Good and evidence about existence of Good one of them it was discuss for many people that are disagree with this kind of true.

fifth way, about the end of things, this it was be one of most issue along time this one speaks about how things without reason know what do they have to do...
like flowers, they know that needs sun to get alive and convert ligth energy to chemical energy.
and this is sort of strange because anybody tells them to realized it. so what do they`s do that?

It`s a mistery but, object about article is refered to second way about causality.
that one says
"one thing can`t move him self  because breaks contradiction rule"

The solution of saint Tomas is that must be a cause doesn`t be caused.
 He calls unmoved engine...the name engine means a metaphor to get to know this concept because we aren`t able to get learn infinity category because this is above our intellect at leats to understand well this topic.

so to believers is easy know this true by faith but to not believers think he say this to intuit in the other hand that should exist GOOD.
