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 referenced as movement or work), self-preservation and self-development, orientation, exploration, order, communication, abstraction and imagination, concentration – repetition – self-perfection, and exactness and precision. The human tendencies act as intrinsic powers within individuals, and the relationships among them are dynamic, synergistic, and interdependent.
