Machine summary: It is not possible for you to express a proposition, opinion or belief on your tongue or pen and express it in any way, unless a person who has the power of mental analysis comments on that proposition, opinion or belief and finds out that this belief or opinion Or the proposition contains a series of implicit and unspoken presuppositions. The fact that sometimes I use proposition and sometimes belief or belief is because the meaning of proposition is different from belief and belief, but in this discussion where I want to briefly present some points, I must consider a single meaning for these two categories. There is a difference between a proposition on the one hand and an opinion and belief on the other hand.I will summarize these four positions: First position, why did this opinion emerge in your mind and was concluded? What causes and factors caused the owner of the opinion to have this particular opinion? Secondly, why did you express the opinion that was concluded in your mind and did not let it remain hidden in your mind and consciousness, why did you express it on your tongue or pen? The third place is how do you know whether this belief is true or false, in other words, is it true or false? Fourth, what are the effects and results of believing in this belief?In other words, regardless of whether it is right or wrong, if someone or people, individually or socially, believe in this belief, what collective or individual, internal or external, positive or negative, good or bad effects will result from it? These four positions are very different and distinct from each other
