发帖数: 76 | 11 MYTH: Separation of church and state is not in the U.S. Constitution.
FACT: It is true that the literal phrase "separation of church and state" does
not appear in the Constitution, but that does not mean the concept isn't
there. The First Amendment says "Congress shall make no law respecting an
establishment of religion or prohibiting the free exercise thereof...."
What does that mean? A little history is helpful: In an 1802 letter to the
Danbury (Conn.) Baptist Association, Thomas Jefferson, th |

发帖数: 76 | 12 MYTH: Thomas Jefferson's 1802 letter to the Danbury Baptists was a mere
courtesy and should not be regarded as important.
FACT: Religious Right activists have tried for decades to make light of
Jefferson's "wall of separation" response to the Danbury Baptists, attempting
to dismiss it as a hastily written note designed to win the favor of a
political constituency. But a glance at the history surrounding the letter
shows they are simply wrong.

FACT: Those who make this assertion confuse the founding of the United States
as a political unit with the settlement of North America. It is true that a

dissenters who sought freedom to worship. Many of these people believed they
were establishing some type of Christian utopia, and many supported religious
liberty only for themselves. Most of the early colonies were th |

FACT: In the Supreme Court's 1892 Holy Trinity Church v. United States

Brewer's statement occurred in dicta, a legal term meaning writing that
reflects a judge's personal opinion, not an official court pronouncement that
sets legally binding precedent.
Historians debate what Brewer meant by the statement, some claiming that he

the church, not to bar religious groups from co-opting the government.
FACT: Jefferson and Madison held an expansive view of the First Amendment,
arguing that church-state separation would protect both religion and
government.
Madison specifically feared that a small group of powerful churches would join
together and seek establishment or special favors from the government. To
prevent this from happening, Madison spok |

FACT: Atheist leader Madalyn Murray O'Hair played no role in the Supreme
Court's school prayer decision of 1962.
In the Engel v. Vitale case, the U.S. Supreme Court ruled 8-1 against New
York's "Regents' prayer," a "non-denominational" prayer state education
officials had composed for public schoolchildren to recite.

first must have caused the second. (The phrase is Latin for "after this,
therefore on account of this.")
It is true that some indices of school performance have decreased since 1962,

Illinois Supreme Court, for example, declared mandatory public school
religious exercises unconstitutional in 1910. By the time of the Engel

Is evolution a fact or a theory?
The theory of evolution explains how life on Earth has changed. In scientific
terms, "theory" does not mean "guess" or "hunch" as it does in everyday usage.
Scientific theories are explanations of natural phenomena built up logically
from testable observations and hypotheses. Biological evolution is the best
scientific explanation we have for the enormous range of observations about
the living world.

Most Westerners know very little about the Middle East and the people that
live there. This lack of knowledge hurts our ability to understand, and
engage in intelligent discussion about, current events.
For example, frighteningly few know the difference between Sunni and Shia

interchangeable. They aren’t. So here’s a very brief primer aim |

发帖数: 12461 | 39 这点很重要啊。因为dimension会改变，如果不在原始数据还在etl的时候和fact联合的
