Which philosopher invented the idea that today's me is under tyranny of yesterday's me actions?

I found it year ago on existentialcomics, I think there was here a case in court where accused one said "it wasn't me, it was yesterday's me, I'm not guilty"

Kant discusses it in the *Critique of Practical Reason*, albeit in a more abstract way. 

According to him, freedom is impossible for a being determined in time (as our phaenomenal selves are) because the form of time implies the transcendental law of causality, whereby each phaenomenon suceeds another necessarily according to a rule. 

Hence, your actions (which are phaenomena) are merely a consequence of those that came before. However, your phaenomenal self is the mere sum of every action happening in a certain time. Therefore, none of your actions are caused by you -- they are result of who you were instants ago, which is something you're not.

But freedom is being the sole cause of your actions. Thus, there is no such thing as freedom for a temporal being. 

The one way to allow for freedom is to postulate a non-empirical, a noumenal self. This one, metaphysically connected with your phaenomenal self, is outside time, and hence can be transcendentally free. Although we never experience our noumenal selves, and thus never experience a free will as the cause of our actions, we can still think of it as such.

Therefore, it may be that natural necessity is the sensible cause of action, but free will is its intelligible cause.
