Abstract: “Thought” and “philosophy” are two universal concepts encountered in the study of philosophy. However, how are “thought” and “philosophy” possible? What is the relationship between the two? Generally speaking, “thought”, as the essential attribute of mankind, is a relatively stable theory based on rational thinking. “Philosophy”, as a learning of “love of wisdom”, studies “fact” and “value” on a transcendental level based on the reflection of “thought”. The true “freedom” of “thought” is that “thought” obeys the rules set by itself, so “philosophy” should set the rules for “thought”, that is, “legislation”. Therefore, the relationship between the two is: “thought” is the basis of “philosophy”, and “philosophy” comes from “thought”; “philosophy” legislates for “thought”, and “philosophy” is the “head” of “thought”.

Key words: thought, philosophy, freedom, basis, legislation
