The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.

线性的威力是,一个方程，如果它是个线性方程，那么我就不用再去解他了。

Remember, Newton said F = ma, but didn't tell you what value F has in a given context.

记住,牛顿只说 F = ma,但却没告诉你 F 在特定条件下的值是多少

So isn't f already a float?

所以f不是已经是个浮点数了吗？

If we could find the right F, and make out the argument, the physicalist can't explain it or does a bad job of explaining it and the dualist does a better job of explaining it, we'd have reason to believe in the soul.

如果我们能找到合适的特性F,并且给出论证,物理主义者无法解释,或者解释得很牵强,而二元论的解释更合理,那么我们就有理由相信有灵魂存在
