Some definitions of logic:
1. The branch of philosophy that analyses inference
2. Reasoned and reasonable judgment
3. The principles that guide reasoning within a given field or situation
4. The system of operations performed by a computer that underlies the machine's representation of logical operations
5. A system of reasoning
From a reading of the definitions, can it be inferred that there should be an universal logic which has to be accepted by all?
Logic is based on perception and inference... perception is again based on values, attitudes and reaction...
values - some are inculcated, some are external and some are self learnt
attitude - resulting behaviour of perception + situation
reaction - impact of attitude on values and perception
These are all ever changing depending on the mind of the individual... That is why to each his reasoning... if only we want conformity, the question of acceptance arises...
