Alcácer Do Sal
Alcácer do Sal () is a municipality in Portugal, located in Setúbal District. The population in 2011 was 13,046, in an area of 1,499.87 km2. History Earliest settlement There has been human settlement in the area for more than 40,000 years; archaeological investigations have placed human presence here back to the Mesolithic Period, when the first peoples began to concentrate in the areas around Alcácer. This period was characterized by exploitation of the ecosystem in the Sado Estuary, when the river extended to São Romão, involving fishing, scavenging for shellfish, hunting and foraging in the local forests. The primitive tools, made from chert, were adapted from the techniques of the late Paleolithic era. By the late Mesolithic period, people had concentrated in the area of Comporta and Torrão, later establishing primitive defensive protection to support their communities. These principal settlements were abandoned by the Copper Age, but repopulated during the Ir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metaphysics
Metaphysics is the branch of philosophy that examines the basic structure of reality. It is traditionally seen as the study of mind-independent features of the world, but some theorists view it as an inquiry into the conceptual framework of human understanding. Some philosophers, including Aristotle, designate metaphysics as first philosophy to suggest that it is more fundamental than other forms of philosophical inquiry. Metaphysics encompasses a wide range of general and abstract topics. It investigates the nature of existence, the features all entities have in common, and their division into categories of being. An influential division is between particulars and universals. Particulars are individual unique entities, like a specific apple. Universals are general features that different particulars have in common, like the color . Modal metaphysics examines what it means for something to be possible or necessary. Metaphysicians also explore the concepts of space, time, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Logic
Logic is the study of correct reasoning. It includes both formal and informal logic. Formal logic is the study of deductively valid inferences or logical truths. It examines how conclusions follow from premises based on the structure of arguments alone, independent of their topic and content. Informal logic is associated with informal fallacies, critical thinking, and argumentation theory. Informal logic examines arguments expressed in natural language whereas formal logic uses formal language. When used as a countable noun, the term "a logic" refers to a specific logical formal system that articulates a proof system. Logic plays a central role in many fields, such as philosophy, mathematics, computer science, and linguistics. Logic studies arguments, which consist of a set of premises that leads to a conclusion. An example is the argument from the premises "it's Sunday" and "if it's Sunday then I don't have to work" leading to the conclusion "I don't have to wor ...
