Many people love to opine about happiness. The Christian believes it is adherence to Jesus Christ. The humanist believes it is the protection and advancement of the human species. The environmentalist believes it is the recognition of all species as being equally important. In Buddhism, happiness is achieved when a person can perceive the true nature of reality, unmodified by the mental constructs we superimpose upon it. In Hinduism, there are two types of happiness, one which comes from what they refer to as "the good life" (pleasure and achievement) while the second comes directly from god. The concept of happiness in Islam is known as falah. Falah is pleasure and peace that can be enjoyed by any individuals in life and after life. Even nihilists have their own concept of happiness, "For Nietzsche, the famous mustachioed nihilist, happiness is a kind of control one has over their surroundings. ... That sense of self can then turn into happiness. The problem, of course, is that the only similarity we see between all of these versions of happiness is that they are vastly different from one and other. This is complicated even further when we think of things like sects, cults, revolutions in thought, culture clashes, and independent movements and sub movements within these various modes of thought. Christianity, for example, is one of the most popular religions in the world, not because of its cohesiveness, but because it is so diverse, "Estimations show there are more than 200 Christian denominations in the U.S. and a staggering 45,000 globally, according to the Center for the Study of Global Christianity." Islam, though often presented as a monolithic force by American media, is also quite diverse. Here are just a few denominations of Islam: Sunni Islam, Shia Islam, Kharijite Islam, Murijite Islam, Mutazila Islam, Sunni, Shia, and Ibadi are just a few examples. Then there is nihilism, which also has various schools of thought: moral, epistemological, cosmic, and existential nihilism are the main four, but there are subcategories within these. So, we have a lot of different voices arguing over what happiness is. We have no clear definition of it or what it may be. And, as a result, we have not concrete way of achieving it, unless we look at the science. Neuroscience is telling us something quite different than other modes of thought on the subject. Neuroscience believes that they key to happiness is actually seeking, a human drive that leads to things such as philosophy and artistic expression, but also the setting of goals. It may very well be that the setting of these goals is what makes us happy, not a particular accomplishment or worldview, but the process of seeking those things. If you disagree with my premise, then consider this: "In an American study of mortality in former psychiatric outpatients, the most educated group (and, by implication, those with higher incomes) had the greatest increased risk of unnatural death, and the largest category of unnatural deaths was suicide." And also this, "People with a history of mental illness and a high income are at greater risk of committing suicide than their lower income counterparts. Richer people with a mental disorder may be more suicidal before they are admitted to hospital or they may feel more stigmatised,4 vulnerable, and shameful5 about having a mental illness." If happiness was just about achieving goals, then why, exactly, are wealthy people so miserable? Because we seek, therefore we are. If we do not seek, if we have already done everything or at least think that we have, then we really have no reason to exist. Thinking that certainly does not make us happy.
