5. actuality or actual existence.
6. an obvious or accepted fact; truism; platitude.

8. (often initial capital letter) ideal or fundamental reality apart from and transcending perceived experience: the basic truths of life.
9. agreement with a standard or original.
10. accuracy, as of position or adjustment.
11. Archaic. fidelity or constancy.

Knowledge –

1. acquaintance with facts, truths, or principles, as from study or investigation; general erudition: knowledge of many things.
2. familiarity or conversance, as with a particular subject or branch of learning: A knowledge of accounting was necessary for the job.
3. acquaintance or familiarity gained by sight, experience, or report: a knowledge of human nature.
4. the fact or state of knowing; the perception of fact or truth; clear and certain mental apprehension.
5. awareness, as of a fact or circumstance: He had knowledge of her good fortune.
6. something that is or may be known; information: He sought knowledge of her activities.
7. the body of truths or facts accumulated in the course of time.
8. the sum of what is known: Knowledge of the true situation is limited.

Logic –

1. the science that investigates the principles governing correct or reliable inference.
2. a particular method of reasoning or argumentation: We were unable to follow his logic.
3. the system or principles of reasoning applicable to any branch of knowledge or study.
4. reason or sound judgment, as in utterances or actions: There wasn’t much logic in her move.
5. convincing forcefulness; inexorable truth or persuasiveness: the irresistible logic of the facts.

Reason –

1. sound judgment; good sense.
2. normal or sound powers of mind; sanity.
3. Logic. a premise of an argument.
4. Philosophy. a. the faculty or power of acquiring intellectual knowledge, either by direct understanding of first principles or by argument.
5. the power of intelligent and dispassionate thought, or of conduct influenced by such thought.

How do we use Logic and Reason in The Way?

Reason is used in argument and or discussion.
Logic is the art of scientific reasoning, and the tool for reaching justification through known fact.
When applied to argument, reasoning develops ideas.
When logic is applied to those ideas, in conjunction with accurate knowledge, then the original ideas born of reason are used to acquire or develop further, and possibly previously unknown, scientifically accurate knowledge.
