In the grand scheme of things, morality is relative, proof of that is that stealing isn’t wrong or right in every situation, even the concept of right and wrong can be blurry at times, for example, when good actions might have been done for noble causes but ended up provoking unintended negative consequences. Some accept that morality is completely relative, and while that can certainly be true it just isn’t practical for most purposes, after all, fortunately, pretty much everyone everywhere understands that murder (the killing of other people without any appropriated justification) is always wrong, so, not really that relative.
Morality is extremely important in order to build harmonious social relationships but also to guide our rational thought process, proof of that is that a change in morality can lead to very different rational solutions to the same problem.
Example: Let’s say that food distribution issues have been solved throughout the globe but there’s still too little food to feed everyone. A moral person could appeal to a temporary rationing and a temporary increase in taxation for building massive state-funded agricultural facilities that would address the food shortage as quickly as possible, while an immoral person, on the other hand, could appeal to killing all elderly people in order to solve the same issue.
Rationality is very useful and, dare I say, in short supply nowadays, but, without positive and reasonable core values behind it, as evidenced above, rationality can go very wrong.
I hope you got some use out of what was discussed in this series of articles, many people would make much less mistakes if they got used to utilizing only a fraction of this. If you like the idea of thinking more clearly do know that this series of articles should be interpreted as the beginning of a learning curve, not the end.
