Some people cling so strongly to their beliefs that they cannot accept or share the ideas of the others.

Now, let’s have a closer look at the power of belief, and its ability even to harm people.

It is easy to prove that beliefs are almighty and lead to any kind of power.

For example: armies are useless if soldiers do not firmly believe in the cause for which they are fighting, or, if mercenaries do not trust their commander to be victorious.

Similarly, law is useless if people fail to comply with it.

Religious beliefs often turned out to be more powerful than the State.

Therefore, we can assume that beliefs are the crucial power underlying social relations.

Beliefs are traditionally considered to originate in the mind, however, this refers exclusively to their recent origins: in fact, at a deeper level, there is always a power acting in the name of some doctrine.

Today we tend to reject the ability of reason to influence our actions, yet, the scientific progress indicates quite the opposite. 

Scientists actually prove that a certain intellectual attitude may lead to military power and wealth, which were the aims of everyone, therefore this new intellectual attitude prevailed over the obscurantist one, in spite of the power of tradition, the control of the Church and feelings pertaining to the Catholic theology.

Power and limits of fanatic doctrines.

The power and the strength of a community does not only depend on the members or components and on their number, but very much on the economic component, but even more on the doctrine that prophesies and that everyone carries out. Let's see therefore how a fanatical doctrine (and we see even today with the Isis) often increases a community's power.

Today they are trendy, perhaps more than before, their influence on power has great practical importance, so a nation or group of fanatics has odds of success in war, this is a major impediment to democracy and democratic peoples in general; it has more success than a nation where there is a large population of wise men.

Consider this in the light of history.

It is possible to note that cases in which fanaticism led to success are much more known than those in which they failed, because these events remained in the dark.

Certainly a too quickly examination can mislead; it is obvious that if we stay on our guard is easy to avoid it.

A classic example of the fanatic power was that of Hitler's national socialism, but today we have to remember that the maximum fanatic power example is represented by the history of Islam.

Muhammad did not ever add anything to the knowledge and material resources of the Arabs, yet few years after his death they had acquired a vast empire by defeating the powerful neighbours; the religion founded by the Prophet was material and essential element to the success of the nation.
