Quotes by Ernst Haeckel

The whole of nature is a single, living, indivisible unity.
The human soul is nothing but the sum of the functions of the brain.
The cell is the true elementary organism, the fundamental form of all living beings.
The law of recapitulation is the most important general law of organic development.
The human being is only a highly developed mammal, and in no way a special creation.
The history of the development of the individual is a brief and rapid recapitulation of the history of the development of the species.
The cell is the simplest form of life, the fundamental unit of all organisms.
The entire organic world is a single, continuous chain of development, from the simplest to the most complex forms.
The human being, like all other organisms, is a product of natural selection.
The soul is nothing but the sum of the functions of the brain, and therefore subject to the same laws as all other natural phenomena.
The whole of nature is a single, living, indivisible unity, governed by eternal, immutable laws.
The law of recapitulation is the most important general law of organic development, and provides the key to understanding the history of life on Earth.
The cell is the true elementary organism, the fundamental form of all living beings, and the starting point for all organic development.
The human being is only a highly developed mammal, and in no way a special creation, but rather a product of the same natural laws that govern all other organisms.
Monism is the rational connection of all phenomena in a single, all-encompassing world-view, which recognizes no supernatural forces or beings.
The history of the development of the individual is a brief and rapid recapitulation of the history of the development of the species, and thus provides a powerful argument for the theory of evolution.
The cell is the simplest form of life, the fundamental unit of all organisms, and the basis for all biological processes.
The entire organic world is a single, continuous chain of development, from the simplest to the most complex forms, and this development is driven by natural selection.
The human being, like all other organisms, is a product of natural selection, and therefore subject to the same laws of evolution.
