However...
However, there are certain values —good as well as evil— which are of universal nature; they are not confined to one time, place or society. For example, trustworthiness, helping the poor and the weak, working for humanity, and justice. These are considered as good values deeply rooted in the nature of man. Likewise, cheating, selfishness, and injustice are considered as bad at all times and in all places. Such universal values prove the existence of human conscience.
Can conscience alone guide us to perfection through the three dimensions of life? Conscience by itself cannot guide man completely—it needs training. Human conscience is like minerals in the earth which must be extracted and refined. Otherwise, it may be perverted and rendered useless under the influence of a corrupt social environment. Every person is familiar with the situations where he himself or a fellow human being has suppressed the voice of his conscience and given in to his evil desires.
Human Intelligence From the early stages of history, man has been putting forward many ideas for the improvement of human society. But to this day, he has failed to present a plan which would satisfy all requirements of human nature. This is due to the finite nature of our knowledge about the material as well as the spiritual world. Even when man has put forward a good idea, there is no guarantee that it will be implemented properly.
On the individual level, for example, many intelligent and knowledgeable people know the harm of alcoholism, gambling and crime, but nevertheless they fall victims to such practices. On the social and collective level, we have the example of the United Nations Organization with over 150 member countries. But it is a weak world body whose resolutions generally remain merely in the minutes and only on paper. This shows clearly that human intelligence and knowledge are no guarantee for action.
The Divine Guidance Human conscience and intelligence alone are not enough to guide us to the perfection in the three dimensions of life mentioned above. The Divine guidance is the answer: it comes from the unlimited source of knowledge which has no room for error, and its implementation is comparatively more guaranteed because of the dire consequences in the hereafter from which no one can escape.
Conscience and intelligence, with confirmation from the Divine guidance, can help man to reach felicity without danger of corruption or diversion.
