Adaptation is the transformation of an organism by incorporating the environment into its extended cognitive system.

Adaptation is the desire to control environment.

Adaptation is inherent in man. There are no conditions to which a person cannot grow accustomed, especially if he sees that everyone around him lives in the same way.

Adaptation is a necessary faculty of that scoundrel, man. He can grow used to everything.

Change is impossible — The tail of the greyhound will not be made straight even though it remains seven years in the melting-pot.

Change is always possible — Whatever your past has been, you have a spotless future.

Change is unlikely in a great man — A god does not change his ways.

Change is all about timing — It is not best to swap horses while crossing the river.

Conversion is to exhaust one pleasure and seek redemption in another.

Conversion is to execute a mental and moral pirouette from one absurdity to a worse one.

Conversion is to be suddenly seized by fright before a fiction or a fact.

Conversion is a work above man's power. You cannot convert yourself. It is a resurrection from the dead, a new creation, a work of absolute omnipotence.
