Speaking of flawed typing
...let's put it this way, logic as a concept is flawed because it was developed by humans, who are flawed, and illogical. Regarding the wordprocessor example, yes, it can be logically deduced what letters will come out when a certain key is pressed, but what sort of logic are we talking about here? Mathematical, philosophical, symbolic? Also, what if the keyboard is not manufactured properly and the calculated result is not what you expect?
"What we are concerned with in logic is: What is there in a good argument that makes it good, i.e., that makes it so compelling and forceful it is not possible not to believe it."
Therefore, trying to argue both sides is illogical.
