According to etymology, philosophy means "love and wisdom". In academic circles, there is no universally accepted definition of the word philosophy, and it is impossible to foresee the possibility of reaching an agreed definition. As far as western academic history is concerned, philosophy is the study of some problems and the concepts involved.
Historical papers are also a kind of academic papers, which are mainly historical articles with independent opinions on a special issue of history, and are completed through in-depth research. So I think its writing skills should be similar to other papers. First of all, read a lot of the latest articles, screen out the hot keywords that interest you, then pick out what you can understand, make comparative reading and critical reading, then determine the topic, and write half the article well. This link can spend more time, learn from each other's strong points, integrate innovation and combine smoothly. In short, the new things are clear at a glance. Then, to demonstrate adequacy, we should use data and historical facts to speak, use theoretical analysis cases and have problem-oriented macro logic. Then, there is the problem of repetition rate, so we should pay attention to the use of technology. After all, it will involve more quotations, depending on our own grasp.
Literature, philosophy and history are already three major disciplines, and each discipline can be subdivided into many layers, and each layer has countless subclasses, subclasses, subclasses ... divided into countless families. Writing these three papers at the same time is interdisciplinary and spans a very large span.
The three things you want to write are China's philosophy, modern history and modern and contemporary literature.
Modern and contemporary literature, literature first. The word "literature" is vague and deceptive. Let me narrow it down for you. The core of literature mainly includes poetry, novel and drama. So you just need to summarize modern and contemporary poems, novels and plays. This topic is not limited to "China", so it is a very, very large scope. Take poetry as an example. I'll just give you an idea. How has the artistic conception of China's poems developed since the May 4th Movement? For example, there is a node that has changed from the traditional "rhythm" to "cadence" and its essence has not changed. It's all the rhythm of poetry, but the language has changed and the new Chinese needs a new rhythm. Simply put, this thing, your main concern is poetry, novels, scripts and other art forms, and the content is second.
Modern history, the first is history. Just saying "history" usually emphasizes economic history and political history. In other words, only "history" does not include "history of poetry", "history of novels", "history of mathematics", "history of music" and "history of painting". In short, your main concern is, for example, the global economic and political development since19th century.
China's philosophy is first of all philosophy. There is no time limit on this topic, which is terrible. Because this is a very, very specialized field. Ancient philosophy is easy to handle. I can think of two books, Hu Shi's Introduction to China's Philosophy and Qian Mu's History of China Thought. You can refer to their catalogue. But Hu Shi's book ended in the third century BC, and Qian Mu's book ended in the Republic of China, but the history of thought is not a history of philosophy, and few of them can be regarded as philosophy. But modern philosophy does exist, and it can be called philosophy more than those in ancient times.
