People who are truly ignorant are not aware of their ignorance - not being aware that one does not know is a defining quality of ignorance.
Ignorance seems to be a universal condition. In some way and to some degree, we are all ignorant. To a certain extent, we are all victims of illusion. Becoming aware of one's own ignorance is the first step towards getting rid of it.
It is a thinking process, but also one of taking concrete steps in real life. It is an act both of analysis and commitment. Ignorance is the root of suffering. Ignorance is more than just the absence of knowledge, even though a lack of knowledge is often part of the condition. It is the negative opposite of wisdom: the absence of qualities associated with wisdom.
Ignorance also implies a lack of compassion, and as such it constitutes a self-centered attitude and its subsequent destructive approach to life. It is a life of greed and hatred instead of compassion and wisdom. It is to fall victim to illusions of permanence and materialism - the inability to distinguish between the real and the fake, and the failure to choose priorities correctly.
C'mon, c_v, you can't take credit for those words !
