According to Spencer the differences between society and organism are as follows:
(1) In an organism the parts are fixed and bound together in close contact, while in a society the parts are separated and dispersed.
(2) In an organism consciousness is concentrated in one small part, i.e. brain, whereas in society, it is diffused throughout the aggregate. All the members in a society have the capacity for happiness and misery.
(3) In an organism, the parts function for the good of the whole, while a society exists for the good of its members.
(4) Unlike organisms, societies have no specific form, such as a physical body with limbs or a face.
