Immanuel Kant (; German: [I'ma:nue:l kant]; 22 April 1724 - 12 February 1804) was a German philosopher who is a central figure in modern philosophy. Kant argues that the human mind creates the structure of human experience, that reason is the source of morality, that aesthetics arises from a faculty of disinterested judgment, that space and time are forms of human sensibility, and that the world as it is "in-itself" is independent of humanity's concepts of it. Kant took himself to have effected a "Copernican revolution" in philosophy, akin to Copernicus' reversal of the age-old belief that the sun revolves around the earth.
In "Perpetual Peace: A Philosophical Sketch", Kant listed several conditions that he thought necessary for ending wars and creating a lasting peace. They included a world of constitutional republics. His classical republican theory was extended in the Science of Right, the first part of the Metaphysics of Morals (1797). Kant believed that universal history leads to the ultimate world of republican states at peace, but his theory was not pragmatic. The process was described in "Perpetual Peace" as natural rather than rational:  The guarantee of perpetual peace is nothing less than that great artist, nature...In her mechanical course we see that her aim is to produce a harmony among men, against their will, and indeed through their discord. As a necessity working according to laws we do not know, we call it destiny. But, considering its designs in universal history, we call it "providence," inasmuch as we discern in it the profound wisdom of a higher cause which predetermines the course of nature and directs it to the objective final end of the human race.  Kant's political thought can be summarized as republican government and international organization. "In more characteristically Kantian terms, it is doctrine of the state based upon the law (Rechtsstaat) and of eternal peace. Indeed, in each of these formulations, both terms express the same idea: that of legal constitution or of 'peace through law'. Taken simply by itself, Kant's political philosophy, being essentially a legal doctrine, rejects by definition the opposition between moral education and the play of passions as alternate foundations for social life. The state is defined as the union of men under law. The state rightly so called is constituted by laws which are necessary a priori because they flow from the very concept of law. A regime can be judged by no other criteria nor be assigned any other functions, than those proper to the lawful order as such."  He opposed "democracy," which at his time meant direct democracy, believing that majority rule posed a threat to individual liberty. He stated, "...democracy is, properly speaking, necessarily a despotism, because it establishes an executive power in which 'all' decide for or even against one who does not agree; that is, 'all,' who are not quite all, decide, and this is a contradiction of the general will with itself and with freedom." As with most writers at the time, he distinguished three forms of government i.e. democracy, aristocracy, and monarchy with mixed government as the most ideal form of it.

What were the conditions?

His classical republican theory was extended in the Science of Right, the first part of the Metaphysics of Morals (1797).

Marie Charlotte Carmichael Stopes (15 October 1880 - 2 October 1958) was a British author, palaeobotanist and campaigner for eugenics and women's rights. She made significant contributions to plant palaeontology and coal classification, and was the first female academic on the faculty of the University of Manchester. With her second husband, Humphrey Verdon Roe, Stopes founded the first birth control clinic in Britain. Stopes edited the newsletter Birth Control News, which gave explicit practical advice.
During Stopes's time at Manchester, she studied coal and coal balls and researched the collection of Glossopteris (Permian seed ferns). This was an attempt to prove the theory of Eduard Suess concerning the existence of Gondwana or Pangaea. A chance meeting with Antarctic explorer Robert Falcon Scott during one of his fund-raising lectures in 1904 brought a possibility of proving Suess's theory. Stopes's passion to prove Suess's theory led her to discuss the possibility of joining Scott's next expedition to Antarctica. She did not join the expedition, but Scott promised to bring back samples of fossils to provide evidence for the theory. Scott died during the 1912 Terra Nova Expedition, but fossils of plants from the Queen Maud Mountains found near Scott's and his companions' bodies provided this evidence.  In 1907, Stopes went to Japan on a scientific mission. She spent eighteen months at the Imperial University, Tokyo and explored coal mines on Hokkaido for fossilised plants. She published her Japanese experiences as a diary, called "Journal from Japan: a daily record of life as seen by a scientist", in 1910.  In 1910, the Geological Survey of Canada commissioned Stopes to determine the age of the Fern Ledges, a geological structure at Saint John, New Brunswick. It is part of the Early Pennsylvanian epoch Lancaster Formation. Canadian scholars were divided between dating it to the Devonian period or to the Pennsylvanian/Upper Carboniferous period. Stopes arrived in North America before Christmas to start her research. On 29 December, she met the Canadian researcher Reginald Ruggles Gates in St. Louis, Missouri; they became engaged two days later. Starting her work on the Fern Ledges in earnest in February 1911, she did geological field work and researched at geological collections in museums, and shipped specimens to England for further investigation. The couple married in March and returned to England on 1 April that year. Stopes continued her research. In mid-1912 she delivered her results, finding for the Pennsylvanian period of the Carboniferous. The Government of Canada published her results in 1914. Later the same year, her marriage to Gates was annulled.[1]  During the First World War, Stopes was engaged in studies of coal for the British government, which culminated in the writing of "Monograph on the constitution of coal" with R.V. Wheeler in 1918. The success of Stopes' work on marriage issues and birth control led her to reduce her scholarly work; her last scientific publications were in 1935. According to W. G. Chaloner (2005), "between 1903 and 1935 she published a series of palaeobotanical papers that placed her among the leading half-dozen British palaeobotanists of her time". Stopes made major contributions to knowledge of the earliest angiosperms, the formation of coal balls and the nature of coal macerals. The classification scheme and terminology she devised for coal are still being used. Stopes also wrote a popular book on palaeobotany, "Ancient Plants" (1910; Blackie, London), in what was called a successful pioneering effort to introduce the subject to non-scientists.

What research did Stopes do in Japan?
She spent eighteen months at the Imperial University, Tokyo and explored coal mines on Hokkaido for fossilised plants.
