1) Eastern Philosophy Books

Eastern Philosophy Books

Eastern philosophy is the different currents of thought that evolved in South Asia, especially in countries such as China, India and Japan, and in the zones of influence of Islam (from the Iberian Peninsula to Indonesia). It spread from the invasions carried out by Alexander the Great.

This philosophy defended that the phenomena of nature are the answer to the sins committed by the human being. However, philosophers such as Lao Tse, Confucius and Buddha opposed these superstitious beliefs and favored a wisdom of live and let live.

With respect to this type of philosophy, there have been disagreements about calling some currents of Eastern thought “religion“; for example, Buddhism refuses to be labeled as a religion.

2) Empiricism Books

Empiricism Books

Empiricism is a philosophical movement that relies on human experiences as the only one responsible for the formation of ideas and concepts existing in the world. The term empiricism arose in the Modern Age, in the XVII and XVIII centuries, in the United Kingdom.

In this sense, we could establish that empiricism is basically based on two fundamental principles. On the one hand, it carries out the negation of the absolutization of truth, and on the other hand, it makes it clear that all truth must always be put to the test.

Philosophically opposed to rationalism, empiricism was particularly developed by various English philosophers, which is why it is often referred to as “English empiricism”. Some of its main advocates were Bacon, Hobbes, Locke, Berkeley, and Hume.

3) Epistemology Books

Epistemology Books

Epistemology is a branch of philosophy concerned with the study of the nature, origin and validity of knowledge. It studies the foundations and methods of scientific knowledge. To this end, it takes into account historical, social and psychological factors to determine the process of construction of knowledge, its justification and its veracity.

The function of epistemology is to crystallize, i.e., to clarify the circumstances under which knowledge can be acknowledged and its limits, i.e., to determine the scope and validity of knowledge. It uses argumentations as a means to determine the validity or invalidity of knowledge; these can be demonstrative, intuitive, using resources of authority, among others.

When epistemology of medicine, biology or sociology is done, it basically examines the way in which these disciplines study their objects to produce scientific knowledge. Thus, as a study of science, epistemology serves not only the philosopher, but also the scientist.

Philosophy Books for Children

Philosophy, which plays a fundamental role in the formation of committed citizens and with their own judgment, has traditionally been considered a subject too abstract and obtuse for children; it was thought to be a form of knowledge suitable only for the fully developed minds of adults. 

However, in the opinion of numerous experts, children not only can philosophize, but should do so. Among them is Matthew Lipman, philosopher and creator of the Philosophy for Children project, who expressed the following “It is necessary to teach children to philosophize, so they will learn to think and will be able to build a better world, to be active and engaged citizens”.

The Philosophy for Children project and program appeared in the United States at the end of the 1960s and is based on the realization that it is not possible to achieve truly free and supportive societies if we do not have people capable of thinking for themselves within the framework of a supportive and cooperative discussion process.

After Plato’s death in 347 BC, Aristotle decides to go on a journey through different cities in Greece.
