It has been mentioned in this discussion that the progressive person, first chooses a subject of interest and then start analyzing various aspects of that 'interesting' subject. It may seem that this progressive person shall keep himself confined up to the search and positive responsiveness towards only those information sources that are directly related to his own area of interest. This may be true as for as the so called 'professionalism' is concerned but this, however is not true in the case of a progressive person. Progressive approach is different or rather opposite to this so called 'professionalism'. In this professionalism, efforts are made to get expertise/ specialization in only one field of study through reading/ analyzing only those subjects that are directly related to the main field of study. Subjects having no direct link/ relationship with the main field of study are considered to be 'irrelevant'. Study/ analysis of 'irrelevant' subjects are avoided because it is considered just useless for the achievement of the main objective, which is to get expertise or specialization in only one field of study. In this way these 'professionals' willingly keep themselves limited within the framework of their area of 'specialization'.
As previously has been stated that the progressive person not only has to get maximum possible information on the topic, he also has to generate new ideas as well. In this way, he actually has to make 'improvements' and 'expansions' in knowledge. This objective is possible to achieve if his approach is compatible with the optimum functioning system of human mind. For the optimum functioning, human mind can accommodate any amount of information whether relevant or irrelevant provided that too much burden of un-necessary memorization of the 'material objective information' is avoided.
Idea generation process does not require 'material objective information' as its input but idea generation process shall function at optimum level if more and more information, whether relevant or irrelevant to the main subject, is continuously integrated in the mindset. For the optimum functioning of the idea generation process, it is only the 'material objective information' which is not used as input but more and more 'abstract objective or subjective information' however is compulsorily required irrespective of the fact that it has any direct relation with the main subject/ issue or not. Since a progressive person, unlike a 'professional', also has to generate new ideas and since the optimum functioning of the idea generation process requires continuous additions of more and more, relevant or irrelevant information except only un-necessary (i.e. irrelevant) 'material objective information', so in order to generate more new ideas, the progressive person shall not confine himself in getting only the 'relevant' information. He would be requiring 'irrelevant (abstract) information' also for the generation of more new ideas.
Human mind's working principle is the 'identification' of similarities and associations between various sets of information and then manipulating those 'identified' similar or associated sets of information in a way which ultimately results in the formation of 'knowledge'. We know that the concepts of 'similarity' and 'association' do not have any rigid meanings. Human mind is able to identify (or detect) 'similarities' and 'associations' even in those sets of information that belong to totally different or even opposite fields of study. Thus we are able to detect similarities and associations in those two sets of information, let's say, one of which belongs to the study of Ethics and the other belongs to the study of Mechanics. Now consider a person who is a 'professional' in the field of Mechanics and being a 'professional', he considers the study of Ethics to be useless for him because the study of Ethics would be 'irrelevant' to his profession. In this case, since this 'professional' shall not study Ethics so he shall remain unable to identify that 'similarity' or 'association' which exists between the contents of Mechanics and Ethics. Since this 'professional' does not identify the similarity (or association) between different sets of information so no manipulation operation can be performed by his mind because mind can perform manipulation operations only on 'identified' similar or associated sets of information. Since the ultimate result of the manipulation operations by the mind on the 'identified' similar or associated sets of information would have to be the formation of particular 'knowledge', so this ultimate result shall not be taken by this professional because in this case no such manipulation operation has been performed by the mind due to his non-identification of existing similarity or association between the contents of Mechanics and Ethics. In this way this 'professional' shall remain unable to conceive that new idea (most probably this new idea would have to be related to his own area of study) which was possible to be conceived by him if he did not avoid studying Ethics. As a result, this 'professional' actually would be acquiring expertise/ specialization only in already existing theories of his subject and he would not actually be further identifying/ exploring more new issues related to his own subject.
The task before the progressive person is not just to get expertise only in the already existing theories of his subject. The task before him is to move forward. To move forward, by himself, the progressive person has to look forward, beyond the boundary limits of already existing theories. He has to identify more new issues so that he may perform analysis of those newly identified issues. Proper analysis of those new issues is possible to do if the progressive person regularly conceives/ generates new ideas. As previously has been stated that optimum functioning of the idea generation process requires continuous additions of more and more, relevant or irrelevant information except only un-necessary (i.e. irrelevant) 'material objective information'. But only this continuous addition of more and more information of every sort alone cannot stimulate the idea generation process to function at optimum level. Idea generation process can be stimulated for its optimum performance by first having outstanding issues/ problems/ questions etc. in mind and then by regular and continuous acquisition of more and more, relevant or irrelevant information. Here, it should be noted that most of the times, it shall be the acquisition of that 'irrelevant' information that would help in identifying new issues/ problems/ questions relating to the main subject of interest as has been explained in the previously stated example where the professional in the field of Mechanics would possibly become able to find new issues in the subject of Mechanics just if he did not avoid studying Ethics. So the proper sequence of all this process identified here is that first the progressive person shall choose a subject of interest. Then he shall engage himself in acquiring more and more, relevant or irrelevant information. The acquisition of the 'relevant' information shall result in 'linear expansion in knowledge'. The acquisition of 'irrelevant' new information, on the other hand, shall help him in the identification of new issues/ problems/ questions etc. relating to the main subject of interest. By keeping these outstanding issues/ problems/ questions in mind, the progressive person shall continue to engage himself in acquiring of still more and more, relevant or irrelevant information. Now at this time, he would be fulfilling both the essential requirements of the optimum functioning of the idea generation process which are (i) presence of outstanding issues/ problems/ questions etc. in mind; and (ii) regular and continuous acquisition of more and more, relevant or irrelevant information. The new ideas that shall be resulting due to the 'optimum functioning' of the idea generation process in this way would be having the basis, the important component of which was that newly acquired 'irrelevant' information. In this way, the acquisition of 'irrelevant' new information shall ultimately result in 'parallel expansion in knowledge'.
