reasoning consistently to come to a conclusion. If this definition is strictly followed‚ logical thinking cannot be affected by any outside influences as long as the premises are truly valid. For example the syllogism: All mammals are warm blooded. Whales are mammals. Whales are warm blooded. is truly logical because the major premise is true.

KNOWLEDGE‚ our most precious asset‚ is the psychological result of perception and learning and reasoning. Knowledge in short is knowledge about reality; its base is perception and method reason. Hence‚ reason plays a key role being the method. It is an analytic tool for understanding what we perceive and thus contributing to our knowledge. The issue of correct and coherent reasoning is important because it is a way of finding the truth. Reasoning in true sense is guided on the basis of logic. Logic

AIR POLLUTION Air Pollution is another major problem that is yet to be solved. The air is 99.9% nitrogen‚ oxygen‚ water vapor‚ and inert gases. We as humans depend on the air around us to live‚ without it we would die. Although we rely on this as an essential source for living‚ it is still littered and polluted with chemicals. Pollution of the atmosphere and the air around us is air pollution‚ and this is becoming more "popular" everyday. There are several main types of air pollution that include

In F. Scott Fitzgerald’s The Great Gatsby‚ many of the characters were careless and superficial.
