“...the presence of this thing called a soul, and only this thing called a soul, makes a being in the Buffyverse capable of choosing to behave in a profoundly moral way or makes a being capable of redemption.”

“I am perfectly convinced that I have both seen, and heard in a manner which should make unbelief impossible, things called spiritual which cannot be taken by a rational being to be capable of explanation by imposture, coincidence, or mistake.”

“Most women got this thing called compassion. It doesn't make them foolish, just more forgiving. More capable of trying and hoping things worked out.”

“A notorious inability to express emotions makes human beings the only animals capable of suicide.”

“My question is, how and why would a being who has no soul, and no conscience, and no ability to judge between morality and immorality, suddenly become capable of perceiving it [Spike's attempted rap of Buffy] as a "wrong" which needs to be "righted"?”

“human beings do not perceive things whole; we are not gods but wounded creatures, cracked lenses, capable only of fractured perceptions”
