Yes, deductive thinking does start with a given set of rules or premises that are already accepted as true.
Deductive thinking is a logical process of reasoning in which one starts with a general premise or set of premises, and then uses logic to draw a specific conclusion based on those premises. This type of thinking is often used in mathematics, science, and philosophy.
In deductive reasoning, the premises are considered to be true and the conclusion necessarily follows from the premises. For example, if the premise is "All mammals have fur" and the conclusion is "A dog is a mammal", then the conclusion necessarily follows from the premise.
The use of a set of rules or premises is an essential feature of deductive thinking because it allows for logical reasoning and inference to take place. By starting with a set of accepted premises, one can use logic to deduce new information or conclusions.
In summary, deductive thinking does start with a given set of rules or premises that are already accepted as true. These rules or premises are used to draw specific conclusions based on logical reasoning and inference.
