““For once the mind is stirred into motion, it is a slave to that which is driving it. With some things, the beginnings are in our power, but after that they carry us on by their own force, not allowing a return. Bodies allowed to fall from a height have no control of themselves: they cannot resist or delay their downward course, for the irrevocable fall has cut off all deliberation, all repentance; they cannot help but arrive where they are going, though they could have avoided going there at all.””
