What is a logical truth?Logic:Logic is the branch of philosophy concerned with valid inference and correct reasoning principles. Logic has been defined as the "science of correct reasoning." The term "logic" derives from the ancient Greek word logos, meaning "word," which refers to the ...
如果我们将普通的经验真理,比如像“今天下雨”那样的经验真理,还有自然科学中的描述现实世界的真理放在左边,将像“A或者并非A”那样的空洞、与现实世界的实际构成无关的逻辑真理放在右边,那么,将数学视为一种自然科学的观点是“左派”,弗雷格的逻辑主义是 “右...
Conscious experience is a widespread phenomenon. It occurs at many levels of animal life, though we cannot be sure of its presence in the simpler organisms, and it is very difficult to say in general what provides evidence of it. (Some extremists have been prepared to deny it even of mamm...

What's Mathematical Truth 数学真理是什么? 现代物理学告诉我们,宇宙可能是有穷的,时空也可能是离散而非连续的,但在现代数学中我们似乎有着非常确定的、关于某些无穷和连续的数学对象和结构的真理。这些独立于物质世界的数学对象和结构果真存在吗?数学定理果真是关于它们的客观真理?我们的物质性的、有限的大脑又...
What is legal positivism theory? What is experimental pragmatism? What is deductive reasoning? What is pure phenomenology? What is philosophical aestheticism? What is Quine's epistemology? What is Platonism philosophy? What is a logical truth?
Below is the truth table for a NAND operation, and the circuit diagram of a NAND logic gate.NAND A B___ AB 0 0 1 1 0 1 0 1 1 1 1 0NORThe NOR logic operation (which stands for "NOT OR") returns true if its inputs are false, and false if either of its inputs is true....
beliefs. Butit was Aristotle who devised a system of presenting an argument in a logicalform—the syllogism. Logical arguments, he said, consist of two premisesleading to a conclusion. Each step of the argument is a statement, or proposition,in a particular form, such as “All X are Y,”...
A baby’s first steps after crawling is an improvement. Waking up without a stuffy nose for the first time in a week is an improvement. Not burning your dinner for the first time this week is an improvement. But how much improvement is it? These little things may not be so important ...
logical operations are basic operations that can be performed on logical values. these operations include and, or, not, xor, and nand. what is the and operator? the and operator is a logical operation that takes two boolean inputs and returns true only if both inputs are true. in other ...
