“As they are currently practiced, there is no common ground between science and religion… Although just as in hostage negotiations, it’s probably best to keep both sides talking to each other.”

The greatest of people that have ever been in society, they were never versions of someone else. They were themselves.

Honesty is the best policy, in love as in law.

The best apology against false accusers is silence.
