To sum up, I agree with the speaker insofar as the wide acceptance of practicality is considered. Being practical is the tenet of modern society and it does shed light on the wise way of doing things and obtaining goals, no matter in the personal or social level.But the speaker goes too far by claiming that it is the only valuable ideology in society.I am strongly against this idea since in history or at present, we human beings still need the philosophical explanation to clear our goal and to provide motivation. In this aspect, idealism would never be replaced with pure practical consideration. Otherwise,human society will be replete with insensible people directed by economic profit and quick fame and recognition.
