Critical Terminology for Theory of Knowledge
... Typically, what is meant by necessary and sufficient conditions is something stronger: that the conditions are logically necessary or logically sufficient. S is logically sufficient for N if and only if, necessarily, if S, then N; N is logically necessary for S under the same condition. States of a ...

... The hope is that we make valid arguments, where an argument is valid if the truth of the premises implies the truth of the conclusion. We can use rules of logic to make valid arguments. The most common rule of logic is modus ponens (mode that affirms). If A and B be are statements and “if A then B” ...
