Sometimes, when I am doing something charitable for example, I wonder about my sincerity in doing so. Sincerity I feel occurs when the actual act of charity and the motivations of the donor are aligned i.e. that the former actually needs and the latter genuinely wants to do that act of charity without any underlying motive. So when earlier I said I wondered about my sincerity, to be more precise, I meant I contemplated my motivations because they seemed to me vague and obscure. Why did I feel the need to do this? I have many theories all of which at first glance applicable and at second, incomplete. So there is no point in pursuing this.
There is little point in considering a genuine charitable motivation situation because there is no mystery there. There is more interest in considering the 'false' motivation, in the sense that there are other more primary motivations involved, such as to boast about it later, to use charity as a cover for fraudulent purposes, etc. Is an act of charity stained by false motivation? Does it and should it matter to the donee? Are they really in any position to question an act of charity? Can the starving man turn away food from an asshole? And perhaps it is because I don't know I tend to theorize that since I am unsure, the answer was likelier to be found in the 'false' area instead of the 'genuine' area because I cannot say with certainty that I know what it truly means to have a genuine motivation, as I often tend to feel that genuineness means remaining unconsciouos of your motivations, and so the mere act of contemplating it, destroys that genuineness.
All that is left from this is a vague sour feeling sense of guilt but that is easily accounted for.
