{2d05 duratio}

Meaning Lasting (in time). Limited duration is that of a thing coming into existence at some point in time and then at a later point in time gets destroyed. In case an existing thing will never get destroyed, this is very, probably too hard to know, and is NOT called infinite existence but: indefinite existence. Thus duratio is opposed to aeternitas, which is NOT infinite duration, but an entirely different viewpoint, another way to consider and understand things: species aeternitatis.

{2d05 duratio}                                                                                  ... the definition and the introduction and explanation of the term indefinite ...
... Duration is the indefinite continuance of existing. ... Duratio est indefinita existendi continuatio.
... I say indefinite, because it cannot be determined through the existence itself of the existing thing, or by its efficient cause, which necessarily gives the existence of the thing, but does not take it away. ... Dico indefinitam quia per ipsam rei existentis naturam determinari nequaquam potest neque etiam a causa efficiente quae scilicet rei existentiam necessario ponit, non autem tollit.
{2p08 rerum non existentium}                                                    ...some things do not exist ... how about the ideas of them? ...
...The ideas of particular things, or of modes, that do not exist, must be comprehended in the infinite idea of God, in the same way as the formal essences of particular things or modes are contained in the attributes of God. ... ideae rerum singularium sive [mng-eqv] modorum non existentium ita debent comprehendi in Dei infinita idea ac rerum singularium sive [mng-eqv]  modorum essentiae formales in Dei attributis continentur.
{2p08c rerum non existentium ideae non existunt}          ...more about things that do not exist ...
...so long as particular things do not exist, except in so far as they are comprehended in the attributes of God, their representations in thought or ideas do not exist, except in so far as the infinite idea of God exists; and when particular things are said to exist, not only in so far as they are involved in the attributes of God, but also in so far as they are said to continue, their ideas will also involve existence, through which they are said to continue. ...quamdiu res singulares non existunt nisi quatenus in Dei attributis comprehenduntur, earum esse  objectivum sive[mng-eqv] ideae non existunt nisi quatenus infinita Dei idea existit et ubi res singulares dicuntur existere non tantum quatenus in Dei attributis comprehenduntur sed quatenus etiam durare dicuntur, earum ideae etiam existentiam per quam durare dicuntur, involvent.
{2p30 duratione inadaequatam cognitionem}                     ... more about indefinite: a thing's duration does not depend on the thing itself a fortiori it does not depend on its own essence ...  the essence of the interaction of  external things adequately determining the limit of that thing's duration is very hard to know ...
... The duration of our body does not depend on its essence ... nor on the absolute nature of God ... [Our body] is conditioned to exist and operate by causes, which in their turn are conditioned to exist and operate in a fixed and definite relation by other causes, these last again being conditioned by others, and so on to infinity... ... Nostri corporis duratio ab ejus essentia non dependet ... nec etiam ab absoluta Dei natura ... [Nostri corporis] ad existendum et operandum determinatur a talibus causis quae etiam ab aliis determinatae sunt ad existendum et operandum certa ac determinata ratione et hae iterum ab aliis et sic in infinitum ...
{3p08 Conatus tempus indefinitum involvit}                       ... the concepts indefinite and duration at work in the context of conatus...
... The endeavour, whereby a thing endeavours to persist in its own being, involves no finite time, but an indefinite time. ... Conatus quo unaquque res in suo esse perseverare conatur, nullum tempus finitum sed indefinitum involvit
... If it involved a limited time, which should determine the duration of the thing, it would then follow solely from that power whereby the thing exists, that the thing could not exist beyond the limits of that time, but that it must be destroyed; but this ... is absurd ... Wherefore the endeavour wherewith a thing exists involves no definite time; but, contrariwise, since ... it will by the same power whereby it already exists always continue to exist, unless it be destroyed by some external cause, this endeavour involves an indefinite time. ... Si enim tempus limitatum involveret quod rei durationem determinaret, tum ex sola ipsa potentia qua res existit, sequeretur quod res post limitatum illud tempus non posset existere sed quod deberet destrui; atqui hoc ... est absurdum ... ergo conatus quo res existit, nullum tempus definitum involvit sed contra quoniam ... si a nulla externa causa destruatur, eadem potentia qua jam existit, existere perget semper, ergo hic conatus tempus indefinitum involvit ...
