Innate, universal traits that are present in every human being across cultures and ages. As Mario Montessori described, human tendencies act as internal compasses, guiding individuals towards particular ends. The human tendencies include activity (also referred to as movement or work), self-preservation and self-development, orientation, exploration, order, communication, abstraction and imagination, concentration – repetition – self-perfection, and exactness and precision. Human tendencies act as intrinsic powers within individuals. The relationships between the human tendencies are dynamic, synergistic, and interdependent.Innate, universal traits that are present in every human being across cultures and ages.
