What is the shape of a valid argument?

Premise1: If A = B,
Premise2: and B = C
Logical connection: Then (apply principle of equivalence) Conclusion: A = C


A valid argument is one in which...

if the premises are true, then the conclusion must be true also.


Common problems with premises are:

1. They are wrong
2. They do not cover the relevant facts necessary to argue the conclusion
3. One or more premises is an unwarranted assumption.
4. The hidden premise-fallacy


What is meant by rationalisation in terms of making arguments?

In fact, psychological experiments show that most people start with conclusions they desire, then reverse engineer arguments to support them – a process called rationalization.
