What is the difference between logical impossibility and physical impossibility?
To affirm a logical impossibility is to affirm what is self-contradictory, and hence necessarily false; while to affirm a physical impossibility is to affirm merely what happens to be contrary to fact, and hence only contingently false.
What is physical possibility physical impossibility?
Physical Impossibility. Anything that is inconsistent with the laws of nature. Physical possibility vs Logical possibility. Physical possibility is a more limited notion than logical possibility. Whatever is physically possible is logically possible, but not everything that is logically possible is physically possible.
What is a logical impossibility?
Something is logically impossible if it is contradictory, or against the laws of logic. Thus a round square is a logical impossibility, and it is logically impossible to be a tall man without being tall.
What is physical possibility?
Something is a physical possibility if it is allowed by some set of consistent natural laws. Something is metaphysically possible if it is allowed in some possible world. Physical possibilities are a subset of metaphysical possibilities which, in turn, are a subset of logical possibilities.
Is everything that is logically possible also physically possible?
Everything that is physically possible is logically possible, but the converse isn’t true. There is no magic in any physically possible world, because the existence of magic would violate the law of conservation of energy.
What is physical possibility example?
Dying is a physical possibility. Going into an afterlife is a metaphysical possibility. It is a logical possibility that if religion is correct you will live after death.
What is logical possibility example?
You can consider a statement logically possible one if there are no contradictions for it to be true. For example, the statement “Julian is sickly” is considered logically possible since “Julian” and “sickly” is not contradicting each other.
How do you know if something is logically possible?
Logical possibility is usually considered the broadest sort of possibility; a proposition is said to be logically possible if there is no logical contradiction involved in its being true.
What are the laws of logic?
There are three laws upon which all logic is based, and they’re attributed to Aristotle. These laws are the law of identity, law of non-contradiction, and law of the excluded middle. According to the law of identity, if a statement is true, then it must be true.
What does modal mean in philosophy?
A modal is an expression (like ‘necessarily’ or ‘possibly’) that is used to qualify the truth of a judgement. Modal logic is, strictly speaking, the study of the deductive behavior of the expressions ‘it is necessary that’ and ‘it is possible that’.

What is the difference between analytical and empirical?
Empirical Data vs Analytical Data
As mentioned earlier, empirical evidence is gathered during an experiment. Analytical evidence is from data that is already stored, or historical data. In other words, it was gathered through research of past data instead of during a specific experiment or observation.
What is the difference between evidence and empirical evidence?
Empirical evidence is the evidence of the senses, of direct observation or measurement. Compare that to rational evidence, which is evidence that is the result of deduction or other reasoning, or anecdotal evidence which comes from personal testimony (which may be reliable or not).

What are 3 types of empirical evidence?
There are three major types of empirical research:

- Qualitative Methods. e.g., numbers, mathematical equations).
- Mixed Methods (a mixture of Quantitative Methods and Qualitative Methods.
What is empirical evidence in philosophy?
Empirical evidence is the evidence that we directly observe and get from our senses. This might be contrasted to philosophical or theoretical reasoning, which can be done without any direct observation of ‘real life’.
What is empirical theory?
