Logical thinking – thinking that is coherent and logical
According to Dr. Karl Albrecht logical thinking is not a magical process or a matter of genetic endowment, but a learned mental process. It is the process in which one uses reasoning consistently to come to a conclusion. Problems or situations that involve logical thinking call for structure, for relationships between facts, and for chains of reasoning that “make sense.”
