Quote by Alexander Graham Bell
Man is an animal which, alone among the animals, refuses to be satisfied by the fulfillment of animal desires.
Summary
This quote suggests that humans are unique in their capacity for dissatisfaction. While animals are content with fulfilling their basic needs and desires, humans are constantly seeking more. They are not satisfied with mere survival but strive for more meaning and fulfillment in life. This insatiable drive distinguishes humans from other animals and makes them pursue higher aspirations and goals beyond their immediate animalistic instincts.
