There are two kinds of truth: empirical truth and necessary truth. Evidence that is true because of fact and experience is empirical truth. When we imagine something other than what it is, it is contingent, but when a statement that is false but might have some truth to it is called a contingent lie. In contrast, a true statement that could be false is called contingent truth. A statement that is accurate because it is justified is a necessary truth; this type of truth may be legitimate depending on its prior implication. Rationalism represents a wide variety of theories, all of which have the common belief that human reason can provide the final answer to the most essential and vital philosophical questions. The speculation of rationalism is that things are built into the structure of our minds, or our innate ideas. The belief that experience can produce some material for our thinking, and possibly some answers, but that experience cannot teach us anything at all. Opposing conceptions of knowledge based on reason is a theoretical method which insists that all competence is obtained through experience, which is empiricism. Empiricists believe that reason is involved in calculations and logic, but is irrelevant to philosophical questions. Subjectivism derives from a truth depending on the subject and their beliefs; Each individual has their own view on a subject. The claim that what is true for one or more people may not be true for another person or people is relativism; declares that every idea is as good as another. Saying that each idea is as good as another could be the same as saying that one idea is the definitive value
