In 1859 Charles Darwin published a book entitled The Origin of Species. Darwin maintained that the various species of plants and animals as we know them were not originally created in their present form. He said that they gradually "evolved" from very simple forms of life. Every plant and animal endeavors to live and reproduce its kind; but more individuals are born than can find proper nourishment. The result is a "struggle for existence" in which the strongest shove aside or destroy the weak.
Perhaps modern medicine is a hindrance to natural law.
For von Treitschke: Is our age the age of iron; and if the strong vanquish the weak, is it the law of life?
