Human beings in all times and places think about their world and wonder at their place in it.Humans are thoughtful and creative, possessed of insatiable curiosity. 46) Furthermore, humans have the ability to modify the environment in which they live, thus subjecting all other life forms to their own peculiar ideas and fancies. Therefore, it is important to study humans in all their richness and diversity in a calm and systematic manner, with the hope that the knowledge resulting from such studies can lead humans to a more harmonious way of living with themselves and with all other life forms on this planet Earth."Anthropology" derives from the Greek words "anthropos": "human" and "logos": "the study of". By its very name, anthropology encompasses the study of all humankind.Anthropology is one of the social sciences. 47) Social science is that branch of intellectual enquiry which seeks to study humans and their endeavors in the same reasoned, orderly, systematic, and dispassioned manner that natural scientists use for the study of natural phenomena.Social science disciplines include geography, economics, political science, psychology, and sociology. Each of these social sciences has a subfield or specialization which lies particularly close to anthropology.All the social sciences focus upon the study of humanity. Anthropology is a field - study oriented discipline which makes extensive use of the comparative method in analysis. 48) The emphasis on data gathered first - hand, combined with a cross - cultural perspective brought to the analysis of cultures past and present, makes this study a unique and distinctly important social science.Anthropological analyses rest heavily upon the concept of culture. Sir Edward Tylor’ s formulation of the concept of culture was one of the great intellectual achievements of 19th century science. 49) Tylor defined culture as "...that complex whole which includes belief, art, morals, law, custom, and any other capabilities and habits acquired by man as a member of society." This insight, so profound in its simplicity, opened up an entirely new way of perceiving and under standing human life. Implicit within Tylor’ s definition is the concept that culture is learned, shared, and patterned behavior.50) Thus, the anthropological concept of "culture", like the concept of "set"in mathematics, is an abstract concept which makes possible immense amounts of concrete research and understanding.

[A] The influence of maples on the Canadian culture.[B] The token of maples in Canada.[C] Contemplation of global distribution of maples.[D] The triumph of Nokomis over the devils with the help of maples.[E] The popularity of the maple in a favorite myth.[F] The maple signals the approach of fall.The maple smoke of autumn bonfires is incense to Canadians. Bestowing perfume for the nose, color for the eye, sweetness for the spring tongue, the sugar maple prompts this sharing of a favorite myth and original etymology of the word maple.41. __________________The maple looms large in Ojibwa folk tales. The time of year for sugaring-off is "in the Maple Moon." Among Ojibwa, the primordial female figure is Nokomis, a wise grandmother. In one tale about seasonal change, cannibal wendigos - creatures of evil - chased old Nokomis through the autumn countryside. Wendigos throve in icy cold. When they entered the bodies of humans, the human heart froze solid. Here wendigos represent oncoming winter. They were hunting to kill and eat poor Nokomis, the warm embodiment of female fecundity who, like the summer, has grown old.42. __________________Knowing this was a pursuit to the death, Nokomis outsmarted the cold devils. She hid in a stand of maple trees, all red and orange and deep yellow. This maple grove grew beside a waterfall whose mist blurred the trees’ outline. As they peered through the mist, slavering wendigos thought they saw a raging fire in which their prey was burning. But it was only old Nokomis being hidden by the bright red leaves of her friends, the maples. And so, drooling ice and huffing frost, the wendigos left her and sought easier preys, For their service in saving the earth mother’s life, these maples were given a special gift: their water of life would be forever sweet, and Canadians would tap it for nourishment.43. __________________Maple and its syrup Row sweetly into Canadian humor. Quebeckers have the standard sirop d’ erable for maple syrup, but add a feisty insult to label imitation syrups that are thick with glucose glop. They call this sugary imposter sirop de Poteau "telephone-pole syrup" or dead tree syrup,44. __________________The contention that maple syrup is unique to North America is suspect, I believe, China has close to 10 species of maple, more than any country in the world. Canada has 10 native species. North America does happen to be home to the sugar maple, the species that produces the sweetest sap and the most abundant flow. But are we to believe that in thousands of years of Chinese history, these inventive people never tapped a maple to taste its sap I speculate that they did. Could Proto- Americas who crossed the Bering land bridge to populate the Americas have brought with them a knowledge of maple syrup Is there a very old Chinese phrase for maple syrup Is maple syrup mentioned in Chinese literature For a non - reader of Chinese, such questions are daunting but not impossible to answer.45. __________________What is certain is the maple’s holdfast on our national imagination. Its leaf was adopted as an emblem in New France as early as 1700, and in English Canada by the mid - 19th century. In the fall of 1867, a Toronto schoolteacher named Alexander Muir was traipsing a street at the city, all squelchy underfoot from the soft felt of falling leaves, when a maple leaf alighted to his coat sleeve and stuck there. At home that evening, he wrote a poem and set it to music, in celebration of Canada’s Confederation. Muir’s song, "The Maple Leaf Forever," was wildly popular and helped fasten the symbol firmly to Canada.The word "maple" is from "mapeltreow", the Old English term for maple tree, with "mapl" - as its Proto-Germanic root, a compound in which the first "m" - is, I believe, the nearly worldwide "ma", one of the first human sounds, the pursing of a baby’s lips as it prepares to suck milk from mother’s breast. The "ma" root gives rise in many world languages to thousands of words like "mama", "mammary", "maia", and "Amazon." Here it would make "mapl" mean "nourishing mother tree," that is, tree whose maple sap in nourishing. The second part of the compound, "apl", is a variant of Indo-European able "fruit of any tree" and the origin of another English fruit word, apple. So the primitive analogy com pares the liquid sap with another nourishing liquid, mother’s milk. 44
