What Does opposed Mean
The Latin word contrapositio came to Castilian as a contrast . The term refers to the act and result of opposing : confronting or contrasting one thing with an opposite or different one.
For example: "The government analyzes exempting some companies from taxes as opposed to the impediment of increasing rates" , "In contrast to religion, which is based on faith, science is sustained from empirical demonstrations" , "The price of wheat and corn accumulates two weeks of fall, in contrast to soy, which maintains constant growth ” .
It can be said that a sentence A is opposed by a sentence B when it is desired to mark the difference between the two, in such a way that the expression evidences the existing opposition. A and B , in this framework, express the opposite.
Suppose an economist lists the economic achievements of Brazil , Chile, and Uruguay . Then refers to the problems that records the economy of Argentina . The analyst, in this way, postulates the Argentine case ( negative ) as opposed to the experience of Brazil , Chile and Uruguay ( positive ).
The demonstration by contrast , on the other hand, appears in the field of logic . A conditional statement can be contrasted when its terms are negated and the direction of the inference is reversed. Thus, a statement and its contrast are logically equivalent.
The logical contrast , in short, postulates the existence of a logical equivalence between a conditional sentence and its corresponding contrast: "All footballers are athletes" is equivalent to "If he is not an athlete, then he cannot be a footballer . "
