Page "Constructivism (mathematics)" Paragraph 2

Constructivism is often identified with intuitionism, although intuitionism is only one constructivist program.

Intuitionism maintains that the foundations of mathematics lie in the individual mathematician's intuition, thereby making mathematics into an intrinsically subjective activity.

Other forms of constructivism are not based on this viewpoint of intuition, and are compatible with an objective viewpoint on mathematics.
