Famous Quotes By Ernst Haeckel

Ernst Haeckel Quotes 1508478

Civilisation and the life of nations are governed by the same laws as prevail throughout nature and organic life. — Ernst Haeckel

Ernst Haeckel Quotes 1752432

An irrefutable proof that such single-celled primaeval animals really existed as the direct ancestors of Man, is furnished according to the fundamental law of biogeny by the fact that the human egg is nothing more than a simple cell. — Ernst Haeckel

Ernst Haeckel Quotes 294821

The real cause of personal existence is not the favor of the Almighty, but the sexual love of one's earthly parents. — Ernst Haeckel

Ernst Haeckel Quotes 1201073

Politics is applied biology. — Ernst Haeckel

Ernst Haeckel Quotes 1910886

The whole of organic nature on our planet exists only by a relentless war of all against all ... The raging war of interests in human society is only a feeble picture of an unceasing and terrible war of existence which reigns throughout the whole of the living world. — Ernst Haeckel

Ernst Haeckel Quotes 1638056

Phylogeny and ontogeny are, therefore, the two coordinated branches of morphology. Phylogeny is the developmental history [Entwickelungsgeschichte] of the abstract, genealogical individual; ontogeny, on the other hand, is the developmental history of the concrete, morphological individual. — Ernst Haeckel

Ernst Haeckel Quotes 248547

We are compelled by reflection to recognize that God is not to be placed against the material world [as in Christianity], but must be placed as a 'divine power' or 'moving spirit' within the cosmos itself ... All the wonderful phenomena of nature around us, organic as well as inorganic, are only various products of one and the same original force. — Ernst Haeckel

Ernst Haeckel Quotes 1720726

Haekel's reasoning is simple: humans are nature, they are part of, and a result of, evolution. Our actions and our thoughts are products of this evolution. Accordingly, when humans come to know something, ultimately it reveals their own nature. Our knowledge
which has developed in and is subject to the laws of nature
is in itself nature (and according to Haeckel, nothing more.) The draftsman, his sensory organs, his motor activity, are results of a development with which, in the end, nature merely represents itself. — Ernst Haeckel

Ernst Haeckel Quotes 521109

Man is not above nature, but in nature. — Ernst Haeckel

Ernst Haeckel Quotes 2044477

By ecology we understand the total science of the connections of the organism to the surrounding external world. — Ernst Haeckel

Ernst Haeckel Quotes 973110

I established the opposite view, that this history of the embryo (ontogeny) must be completed by a second, equally valuable, and closely connected branch of thought - the history of race (phylogeny). Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation ... 'ontogenesis is a brief and rapid recapitulation of phylogenesis, determined by the physiological functions of heredity (generation) and adaptation (maintenance). — Ernst Haeckel

Ernst Haeckel Quotes 2163289

In the course of individual development, inherited characters appear, in general, earlier than adaptive ones, and the earlier a certain character appears in ontogeny, the further back must lie in time when it was acquired by its ancestors. — Ernst Haeckel

Ernst Haeckel Quotes 169163

Mental differences between the lowest men and the animals are less than those between the lowest and the highest man. — Ernst Haeckel

Ernst Haeckel Quotes 1913834

It is, however, a most astonishing but incontestable fact, that the history of the evolution of man as yet constitutes no part of general education. Indeed, our so-called 'educated classes' are to this day in total ignorance of the most important circumstances and the most remarkable phenomena which Anthropogeny has brought to light. — Ernst Haeckel

Ernst Haeckel Quotes 1748863

Nothing is constant but change! All existence is a perpetual flux of "being and becoming!" That is the broad lesson of the evolution of the world. — Ernst Haeckel

Ernst Haeckel Quotes 1596484

Among the Spartans all newly born children were subject to a careful examination or selection. All those that were weak, sickly, or affected with any bodily infirmity, were killed. Only the perfectly healthy and strong children were allowed to live, and they alone afterwards propagated the race. — Ernst Haeckel

Ernst Haeckel Quotes 1513391

There is no doubt that the course and character of the feared 'European war' ... will become the first world war in the full sense of the word. — Ernst Haeckel

Ernst Haeckel Quotes 1173651

The nucleus has to take care of the inheritance of the heritable characters, while the surrounding cytoplasm is concerned with accommodation or adaptation to the environment. — Ernst Haeckel

Ernst Haeckel Quotes 1111315

The succession of individuals, connected by reproduction and belonging to a species, makes it possible for the specific form itself to last for ages. In the end, however, the species is temporary; it has no "eternal life." After existing for a certain period, it either dies or is converted by modification into other forms. — Ernst Haeckel

Ernst Haeckel Quotes 1081171

The ancestors of the higher animals must be regarded as one-celled beings, similar to the Amoebae which at the present day occur in our rivers, pools, and lakes. The incontrovertible fact that each human individual develops from an egg, which, in common with those of all animals, is a simple cell, most clearly proves that the most remote ancestors of man were primordial animals of this sort, of a form equivalent to a simple cell. When, therefore, the theory of the animal descent of man is condemned as a 'horrible, shocking, and immoral' doctrine, tho unalterable fact, which can be proved at any moment under the microscope, that the human egg is a simple cell, which is in no way different to those of other mammals, must equally be pronounced 'horrible, shocking, and immoral. — Ernst Haeckel

Ernst Haeckel Quotes 1060995

In consequence of Darwin's reformed Theory of Descent, we are now in a position to establish scientifically the groundwork of a non-miraculous history of the development of the human race ... If any person feels the necessity of conceiving the coming into existence of this matter as the work of a supernatural creative power, of the creative force of something outside of matter, we have nothing to say against it. But we must remark, that thereby not even the smallest advantage is gained for a scientific knowledge of nature. Such a conception of an immaterial force, which as the first creates matter, is an article of faith which has nothing whatever to do with human science. — Ernst Haeckel

Ernst Haeckel Quotes 999658

Man is not distinguished from [the animals] by a special kind of soul, or by any peculiar and exclusive psychic function, but only by a higher degree of psychic activity, a superior stage of development. — Ernst Haeckel

Ernst Haeckel Quotes 806869

The cell never acts; it reacts. — Ernst Haeckel

Ernst Haeckel Quotes 503490

Both of these branches of evolutionary science, are, in my opinion, in the closest causal connection; this arises from the reciprocal action of the laws of heredity and adaptation. — Ernst Haeckel

Ernst Haeckel Quotes 441547

As our mother earth is a mere speck in the sunbeam in the illimitable universe, so man himself is but a tiny grain of protoplasm in the perishable framework of organic nature. [This] clearly indicates the true place of man in nature, but it dissipates the prevalent illusion of man's supreme importance and the arrogance with which he sets himself apart from the illimitable universe and exalts himself to the position of its most valuable element. — Ernst Haeckel

Ernst Haeckel Quotes 296398

Where faith commences, science ends. Both these arts of the human mind must be strictly kept apart from each other. Faith has its origin in the poetic imagination; knowledge, on the other hand, originates in the reasoning intelligence of man. Science has to pluck the blessed fruits from the tree of knowledge, unconcerned whether these conquests trench upon the poetical imaginings of faith or not. — Ernst Haeckel
