Idealism, as defined by the lexicon, is an ideal state at which the laws of nature and science assume perfection. At such conditions, results produced and conclusions drawn are so fine and accurate that it has become an obsession for humans, who have been putting their endeavour, assiduous efforts and mental cerebration en bloc and en masse, to achieve this ideal state. However, such ideal state cannot be attained practically, the reasons for which may be attributed to natural forces, certain flaws in machinery and assumptions used while deriving the laws. Additionally, humans have been working obstinately for attainment of ideality, and since attaining an ideal state is almost impossible for humans thus, such demeanour at times leads to disappointment and frustration.
Humans today, by the dint of their cogitation and research have ameliorated the gamut of their ken and cognizance. A considerable amount of study and research work has been accomplished in each and every field that is known to us today, and humans have always tried to achieve conditions that are in close proximity with ideal mathematical relationships and calculated statistical data. However, practical and real-time conditions cannot match the calculated conditions, because while calculation of results and formation of theories many assumptions are taken into consideration, and it is not possible to maintain the applicability of suppositions and assumptions practically. Moreover, the devices and instruments used to prove the verity of laws, are themselves imperfect and non-ideal, and hence the results and conclusions. Citing an example to bolster the above stated facts, in the field of economics while deriving the Law of Demand and Supply, many assumptions such as, wealth and income of people remain constant, value of the assets remains constant et al are used. However, such assumptions do not hold true in the real world, probably because the wealth and income of a person change from time to time and the value of assets may fluctuate repeatedly, due to which achieving the supposed ideal conditions becomes somewhat difficult. In addition to this, if an economist prognosticates the rate of increase of the demand of a particular product, it may differ by some amount practically which can be solely imputed to market forces and the price of other products as well. Hence one can clearly ascertain that, achieving idealism is a cumbersome task and if one sticks to ideality, it may engender faulty conclusions and results which finally lead to frustration and disappointment.
Another example that can substantiate the above stated facts is, while deriving the graphical characteristics of devices such as diodes and transistors, assumptions such as, current through the device or voltage across the device remain constant are used. However, owing to the internal structure of devices and their discontinuous behaviour at different voltages and currents, the observed characteristics are bound to differ substantially from the calculated characteristics. If one continues to assume the ideal behaviour to be correct, then discrepancies and faulty results may be produced, which may arise troubles and disappointment in the long run.
Hence, in summary; idealism although admirable, is extremely difficult to achieve because the laws and devices fail to retain the ideal behaviour under practical circumstances. Nevertheless, humans in spite of being fully aware of the fact will continue to work indefatigably and obstinately to achieve the ideal state and perfection. However, owing to the irascible behaviour of humans such temperament will finally lead to frustration and disappointment.
