Intelligence Defined

"Men are often called intelligent wrongly.  Intelligent men are not those who are erudite in the sayings and books of the wise men of old, but those who have an intelligent soul and can discriminate between good and evil.  They avoid what is sinful and harms the soul; and with deep gratitude to God they resolutely adhere by dint of practice to what is good and benefits the soul.  These men alone should truly be called intelligent."  (from On the Character of Men, in the Philokalia, Vol 1)
