Axiom: It is a truism that all people want to be happy.
Definition: Happines is to be defined as a state of prolonged positive emotion.
Question: How is happiness to be achieved.
Hypothesis: Through acquisition of inner peace. We are more likely to remain happy if we maintain emotional composure. It is better to stay moderately excited for a long period of time than attempt to seek great excitement. Doing the latter will lead to an emotional instability, as it is difficult to maintain a high level of excitement consistently. In the end we want to be in control over our emotions in order to keep the peace. If we are in control, it will be easier for us to elect how our inner world shall be maintained. In order to acquire such a control, man must be moderate in his passions.
This is the doctrine famously championed by Aristotle earlier concerning the necessity of moderation. The more man focuses on dispassionate contemplation, the easier it will be for him to avoid strong emotions simply because he shall not focus on them at great length. He shall come to terms with his emotions by dispassionately analyzing them. Once they have been understood, they shall cease to have a force which could disturb his dispassionate contemplation and quest for emotional equillibrium.
This is how man is to find peace in his inner life. The outer life, however, may prevent him from achieving this, as if there is not an orderly environment around him, he may not be in the position to pursue inner growth. An Ideal society need not necessarily be comprised of deep thinkers, but of individuals who prefer to handle things in a dispassionate way. Akin to what we may call individuals with a Thinking preferrence who use this faculty well habitually. Feelers are undesirable because their relationship to emotion is analogous to that of a magnet to metal. They shall spark passions in all of us rendering emotional equillibrium close to impossible.
