What is the difference between logic and rationality?

Question

How are they related?

Answer 1

Logic is a definition of what is considered rational. Logic puts rules around what we all know intuitively to be rational.

It's like the difference between syntax and language.

Answer 2

First you need to understand the definition of each word, to be able to see the differences and percieve the relationship between Logic an Rationality

Excerpts from Wikipedia...
Logic, from Classical Greek λόγος logos (the word), is the study of patterns found in reasoning. The task of the logician is to set down rules for distinguishing between valid and fallacious inference, between rational and flawed arguments.

Rationality as a term is related to the idea of reason, a word which following Webster's may be derived as much from older terms referring to thinking itself as from giving an account or an explanation. This lends the term a dual aspect. One aspect associates it with comprehension, intelligence, or inference, particularly when an inference is drawn in ordered ways (thus a syllogism is a rational argument in this sense). The other part associates rationality with explanation, understanding or justification, particularly if it provides a ground or a motive. What is irrational, therefore, is defined as that which is not endowed with reason or understanding.

Rationality and logic
A logical argument is sometimes described as rational if it is logically valid. However, rationality is a much broader term than logic, as it includes "uncertain but sensible" arguments based on probability, expectation, personal experience and the like, whereas logic deals principally with provable facts and demonstrably valid relations between them. For example, ad hominem arguments are logically unsound, but in many cases they may be rational. A simple philosophical definition of rationality refers to one's use of a "practical syllogism". For example,

I am cold
If I close the window I will not be cold
Therefore, I closed the window
We should note that standard form practical syllogisms follow a very specific format and are always valid if constructed correctly though they are not necessarily sound. There are several notable implications of such a definition. First, rationality is objective - it exists only when a valid practical syllogism is used. Second, a choice is either rational or it is not - there is no gradation since there is no gradation between valid and invalid arguments. Third, rationality only applies to actions - i.e. shutting the window is a rational thing to do if you are cold (assuming it is cold outside). Evidence bears on belief but not on rationality. All that is required for an action to be rational is that you believe that X and that if X then Y so you do Y. Arguments about belief are couched in the terms valid and sound - logically you must believe something if the argument supporting it is sound. In some cases, such as religious belief, the argument may be valid but its soundness cannot be known for the truth of its premises cannot be known.

Answer 3

I believe that logic is a solution that you get through...say calculating. In other words you have proof that this solution is true and therefore logically, it is true. Rationality is more like continuing to think of a solution for something and then finally settling on that solution. Not exactly having proof that the chosen solution is better or worse than the one not chosen. If that makes any sense.

Answer 4

Logic is purely formal, and has nothing to say about basic premises. An argument based on false premises can thus be valid without being true. Rationality is generally based on logic, but begins from some established known.

Answer 5

good judgment is a extra systematic way of questioning, the place you detect a sloution to he situation in a step by means of step way. it relatively is predicated extra on info. Rationality is a a lot wider time era than good judgment it consists of (uncertain yet sensible), and refers to arguments in line with possibility, expectation, very own adventure etc while good judgment bargains chiefly with provable info Logical is often rational, yet rational isn't continually a hundred% logical.

Answer 6

Rationality is the use of logic to solve problems -- meaning to apply rules of inference to observed data in order to reach a sound conclusion.

Answer 7

Logic is a part of philosophy, all about argumenting
Rationality is related to thoughts, and logically true (I think?)

That's all I know

I'm not as much of a philosopher as you are so sorry

Answer 8

I think one needs to be rational to follow logic. Irrationality is simply an inability to think logically.

Answer 9

Very simple:

Logic+Science=Rationality

Answer 10

They basically mean the same thing.
