Age Of Enlightenment Under Attack

Our modern society is based on "age of enlightenment" values. This means the values of personal liberty, tolerance and the use of science and reason to find the truth.
Now these values are under assault, both within and outside of the West. Most vividly this can be seen in the Arab world, where tolerance, science and freedom are in very short supply.
But, we also see an assault on enlightenment values within, both by the religious right and the P.C. left.
This can be seen in the Right who attack Darwin and gay rights as being "ungodly".
Some on the left reject freedom of speech because it may "offend" someone. And "post modernism" states that there is no objective reality, rendering objective science pointless.
The power of ignorance and narrow-mindedness should not be underestimated. They are the greatest threats to both the pursuit of truth and freedom.
