Actually, logic won't help that much.
For instance, if the premises are false, then a logically coherent statement may still be wrong.
eg. all human beings are reptiles, reptiles are cold blooded, therefore human beings are cold blooded.
Or, even when a statement is logically incoherent, the conclusion may still be true.
eg. all human beings are mammals, mammals are warm blooded, therefore snakes are cold blooded.
Logic can only help as a tool to organize knowledge and draw conclusions from that, however, it is sufficient to produce new knowledge in an of itself. For that, other means are necessary. Usually, good arguments will contains both true premises and coherent logic, to draw further true conclusions.
