cannot justifiably speak of facts and relationships between facts…Now, even though the realms of religion and science in themselves are clearly marked off from each other, nevertheless there exist between the two strong reciprocal relationships and dependencies. Though religion may be that which determine the goals, it has, nevertheless, learned from science, in the broadest sense, what means will contribute to the attainment of the goals it has set up." Morality Many religions have value frameworks regarding personal behavior meant to guide adherents in determining between right and wrong. These include the Triple Jems of Jainism, Judaism's Halacha, Islam's Sharia, Catholicism's Canon Law, Buddhism's Eightfold Path, and Zoroastrianism's good thoughts, good words, and good deeds concept, among others. Religion and morality are not synonymous. While it is "an almost automatic assumption," in Christianity, morality can have a secular basis. The study of religion and morality can be contentious due to ethnocentric views on morality, failure to distinguish between in group and out group altruism, and inconsistent definitions of religiosity. Politics Impact Religion has had a significant impact on the political system in many countries. Notably, most Muslim-majority countries adopt various aspects of sharia, the Islamic law. Some countries even define themselves in religious terms, such as The Islamic Republic of Iran. The sharia thus affects up to 23% of the global population, or 1.57 billion people who are Muslims. However, religion also affects political decisions in many western countries. For instance, in the United States, 51% of voters would be less likely to vote for a presidential candidate who did not believe in God, and only 6% more likely. Christians make up 92% of members of the US Congress, compared with 71% of the general public (as of 2014). At the same time, while 23% of U.S. adults are religiously unaffiliated, only one member of Congress (Kyrsten Sinema, D-Arizona), or 0.2% of that body, claims no religious affiliation. In most European countries, however, religion has a much smaller influence on politics although it used to be much more important. For instance, same-sex marriage and abortion were illegal in many European countries until recently, following Christian (usually Catholic) doctrine. Several European leaders are atheists (e.g. France's former president Francois Hollande or Greece's prime minister Alexis Tsipras). In Asia, the role of religion differs widely between countries. For instance, India is still one of the most religious countries and religion still has
