Every song has a composer, every book has an author, every car has a maker, every painting has a painter, and every building has a builder. So it isn't irrational to take this simple logic a little further and say that nature must have had a Maker. It would be irrational to believe that it made itself.
Fear of serious injury alone cannot justify oppression of free speech and assembly. Men feared witches and burnt women. It is the function of speech to free men from the bondage of irrational fears.

We face a conflict between civilisation and culture, which used to be on the same side. Civilisation means rational reflection, material wellbeing, individual autonomy and ironic self-doubt; culture means a form of life that is customary, collective, passionate, spontaneous, unreflective and irrational.
Nothing defines humans better than their willingness to do irrational things in the pursuit of phenomenally unlikely payoffs. This is the principle behind lotteries, dating, and religion.

I'm embarrassed to admit that I'm still scared of the dark. I have to have a light on all night. It's completely irrational, and my son is the same. I just hate the dark.
The fact that logic cannot satisfy us awakens an almost insatiable hunger for the irrational.
When hypocrisy is a character trait, it also affects one's thinking, because it consists in the negation of all the aspects of reality that one finds disagreeable, irrational or repugnant.
