I actually have 3...sort of. I have a regular conscious that yells at me when I've done something/am doing wrong, irresponsible me that is selfish a doesn't care (sadly listen to this one too often), and wise yoda like conscious that analyzes how I could have done thinks better when I'm feeling guiltily for what ever I'd done.
I do have a conscience in that I will feel somewhat bad if I lie, cheat, steal, or hurt someone.I'm also conscious at the moment, seeing as how I'm able to answer this.
