One might say: “Clearly, the idea of reincarnation proceeds merely from wishful thinking—it’s comforting to think that, birth after birth, the soul lives on.”
Comforting? The Vedic writings say that the cycle of birth and death entails repeated miseries. Is birth fun? Is dying your idea of having a good time?
Apart from that, whether the idea gives solace or dread is beside the point. How we feel about things makes no difference as to whether they are true or not.
The objection suffers from the fallacious strategy of attacking one’s supposed motives for holding to a position—in this case, the idea of reincarnation—rather than addressing the position itself.
