You can’t help the feelings you have. You simply have them—until you don’t. Same for your truths. Think of the experience of making a conclusion: you explore two or more rationalized fantasies. You observe how the fantasy strikes you——but you still are subject to your nature. You can’t simply decide to have one feeling about a ‘fantasy’ or ‘truth’ over another.
So we are confronted with a certain paradox: you are completely subjected to your truths, yet you are the sole author of them.
