However, in the case of emotion, it is usually much difficult to really create the link. For instance in making decisions through emotions, one can be driven by such factors like nostalgia while they might be well aware (through cognition) that such a decision is not really the best (Norman, 2005). The traditional hard science approach in decision making faces much antipathy in the conventional practical situation. It relies much on positivism and logical sense. However, in today‚Äôs science, decision making and decision calls for more than mere objectivism. The world is indeed inundated with many situations and options which have made human beings to be accustomed to different experiences. In this regard, in making decisions and designs, it is important to demonstrate a subjective mind that highly promotes experientialism. It is further realized that the reaction of human beings to design normally occurs in three different levels: visceral, behavioral and reflective. The visceral level is very important as it creates the first impression in terms of appearance. In this case, one is attracted by what their see before they can consider such aspects like functionality. Secondly, people are also driven by behavioral factors which include the ability of the item to perform the required needs. Lastly, the reflective level regards the effects of the item on the self-image and satisfaction of the individual. The subjective and post-positivist approach is realized in the design of such products like watches and autos in which case the mere functionality of the item does not really drive people to be interested. In the technological field, image and sound are some of the most fundamental factors that drive people to purchase specific items like computers and phones. The designers of these products should therefore move away from the traditional focus on objectivism and realize the very importance of creating an item which lures people through sight, sound and performance. The products used in everyday life should therefore be designed in a way that evokes certain emotions on the users. Most designers still hold on to the traditional objective ideas regarding science where emotional concerns of the users are not given much consideration in the design process. However, companies like Apple have realized this crucial value and are not only enhancing functionality but also image and visual characteristics of their products. The results are basically the increase in sales as people tend to be attracted visual efficiencies of such products. The subjective orientation places much focus on creating experience on the part of the users. For instance, in information technology, the designers should make products which are identified with specific features such as efficiency. Therefore the present usability design places greater emphasis on such critical factors that create a mental attitude on the part of the consumers who are then driven to purchase such items. PHILOSOPHY–A CRASH COURSE Philosophy is normally a subject of many debates and questions regarding its very nature and its importance in conventional human practice. While some people normally feel that it is almost unnecessary owing to its excessive indulgence in rational argument, the core of the matter is basically with respect to the importance of philosophy in
