Document Summary
In logical reasoning, premise statements describe facts or assumptions that are presumed to be true. An argument is a set of premise statements that are logically combined to yield a conclusion: method of empiricism, uses observation or direct sensory experience to obtain knowledge. The scientific method (more of a cycle evaluate predictions, modify hypothesis try again) Logical/objective method for obtaining info and making decisions based on that info. Inductive reasoning: using small set of observations and forming general statement; increases knowledge piece by piece. Modus ponens if p then q, - truth condition (statement that is true: p observation, therefore, q the conclusion. Example: if a fruit is red, then it is hot; the fruit is a red colour; therefore, it is hot. Step 2: form a hypothesis identify variables associated with observation. Step 3: use hypothesis to get a testable prediction. Deductive reasoning: uses general statement to make conclusions; decreases, breaks down.
