Is that a philosophic, scientific, or mathematic statement? Please answer without mixing or interchanging concepts.
Is a observed fact a faith and belief or a unknown? Is a unknown a scientific fact. Can faith and belief be determined zero by a mathematical equation. Perhaps you should examine your question of opinion. Are the definitions of the sun and moon interchangeable. Is it your opinion that all these things are the same and interchangeable regardless of definition.
Socrates (469-399 B.C.E.) Scorrates first thought the method of philosophy and is the father of philosophy. He was sentenced to death by a Theocratic state rather than change his arguments. He choose death by hemlock rather than refuting his method. The definition of philosophical method can be found in the first chapter of most first year philosophy text books.
Aristotle's Method Aristotle's method of investigation varied from one natural science to another, depending on the problems encountered, but it usually included:
defining the subject matter
considering the difficulties involved by reviewing the generally accepted views on the subject, and suggestions of earlier writers
presenting his own arguments and solutions.
Again, this is the pattern modern research papers follow, Aristotle was laying down the standard professional approach to scientific research. The arguments he used were of two types: dialectical, that is, based on logical deduction; and empirical, based on practical considerations. It has change little except that more evidence and empirical evidence is require to explain the fact. The method is usually defined as I stated earlier in any first year science text book of inquiry.
math·e·mat·ics (mth-mtks) n. (used with a sing. verb) The study of the measurement, properties, and relationships of quantities and sets, using numbers and symbols. The definition can be found in most alimentary math texts. Although Descartes is known as the father of mathematics the origin is unknown. It is ongoing and includes both deducted and inducted reasoning.
