“[It is] useful to know the laws of nature – for that enables us to obey them. To act otherwise would be to rise in revolt against heaven.”
“As in everything, nature is the best instructor.” — Adolf Hitler
-Adolf Hitler, Mein Kampf
“What we must fight for is to safeguard the existence and reproduction of our race and our people, the sustenance of our children and the purity of our blood, the freedom and independence of the fatherland, so that our people may mature for the fulfillment of the mission allotted it by the creator of the universe. Every thought and every idea, every doctrine and all knowledge, must serve this purpose. And everything must be examined from this point of view and used or rejected according to its utility.”
– Adolf Hitler, Mein Kampf (Volume 1, Chapter 8)
“There are certain truths which stand out so openly on the roadsides of life that every passer-by may see them. Yet, because of their very obviousness, the general run of people disregard such truths or at least they do not make them the object of any conscious knowledge. People are so blind to some of the simplest facts in everyday life that they are highly surprised when somebody calls attention to what everybody ought to know.
All the innumerable forms in which the life-urge of Nature manifests itself are subject to a fundamental law–one may call it an iron law of Nature–which compels the various species to keep within the definite limits of their own life-forms when propagating and multiplying their kind. Each animal mates only with one of its own species. The titmouse cohabits only with the titmouse, the finch with the finch, the stork with the stork, the field-mouse with the field-mouse, the house-mouse with the house-mouse, the wolf with the she-wolf, etc.”
