Premise - ANSWER A fact, proposition or statement from which a conclusion is
made
Conclusion - ANSWER A statement or judgment that follows from one or more
reasons.
Conditional Reasoning - ANSWER A conditional statement is, in its most easily
recognized form, an "if...then..." statement. The following is, for example, a conditional
statement. Conditional statements are also described in terms of sufficient and
necessary conditions.
Sufficient - ANSWER An event or circumstance whose occurrence indicates that a
necessary condition must also occur.
Necessary - ANSWER An event or circumstance whose occurrence is required in
order for a sufficient condition to occur.
Explain Sufficient Necessary - ANSWER If a sufficient condition occurs, you
automatically know that the necessary condition also occurs. If a necessary condition
occurs, then it is possible that the sufficient condition will occur, but not certain.
Example of Sufficient Necessary - ANSWER Banging my shin on the table is all
that is needed for me to scream in pain (i.e. it is sufficient), so banging my shin is
considered the sufficient condition. I cannot bang my shin on the table without
screaming in pain (screaming necessarily follows the banging of my shin), so
screaming in pain is the necessary condition. You should be fine if you can simply
remember that the antecedent (the phrase following the "if") is the sufficient
condition for the consequent (the phrase following the "then") and the consequent is
the necessary condition for the antecedent.
, Contra-positive - ANSWER a conditional statement derived from another by
negating and interchanging antecedent and consequent
