Why does any kind of logic exist in the world, unless the world was in some way logical?
The way logic works can be demonstrated as a reductio to its origins.
If you take the expression Cogito ergo Sum , you have a triad consisting in a premise and a conclusion connected by a cnjunction 'ergo'. The' because' is an essential connective
without which the premise and the. conclusion would be
In the triad 'esse est percipii' the set-is- a connector.. Here, est-is the essential term without which the to ideas would be disconnected.
We see an upward logic between the ergo of the first to the certainty of second, without comparing the substantialitys of neither .
Now if we go the other way, and reach the limits of logic connections, where connection are not thought about as related logically, we reach the level of identity. Words are not needed at a certain limits at that level because, identifiable concepts need not signify differences at those levels.
Not that differences of situations do not exist to initiate differentiation of concepts, but these differences are not yet ideational, they are situational.
For example, the difference between the protective hidenness of darkness offer an escape route to a running aborigines trying to escape a pursued trying to identify and capture that human being.
The choice for that being is to stand his ground in the light of day, or escape into the darkness
This is a situational choice, automatic and instinctual in earlier man. The logic of choice is hardwired, and it is determined as a foregone conclusion.
The idea develops from instinctual fear motives to a pre reflexive , to the dual choice, based on the very modern existential triad -esse est percipii. The arrival of the 'is- as the connective between being and awareness is logically turned upside down, from from a prior triad of Cogito ergo Sum.
The logical connection of -is- becomes thought and existence as made certain by logic
Here logic returns a sense of identity, the nature of reason.
The difference is that before the Cogito, consciousness of existence was not differentiated by reason.
Does that mean that prior to the Cogito reason did not exist? No, merely it had no function to connect, because.the idea had not yet differentiated its content-The self.
The logic was a simple awareness based on the fight and flight pronciple from light into the hidenness of darkness.
Logic came first in the form ofn automatic signaling of danger and the necessary action taken in consequence of that danger
The logic built into more sophisticated forms of linguistic communication came much later.
Knowledge through language as an accumulation of information as seen in terms of development of functional applications of the choices through logical channels, then the different forms of logical thinking through experience become uncovered, and discovered.
