When we think about the Human Freedom in idealistic philosophy, we can think that we, human beings, are perfectly free in our Action at the present moment.
But when we think about the Rule of Cause and Effect in materialistic philosophy, we, human beings, can never be free because of being governed by the Rule of Cause and Effect at all.
Therefore generally speaking we, human beings, are always perfectly free, but at the same time we, human beings, are always governed by the Rule of Cause and Effect.
However such a kind of contradictory situation of Human Freedom and the Rule of Cause and Effect can never exist really together actually at all. And so if we want to solve the such kind of contradictory situations, it is necessary for us to leave the intellectual considerations, and we should enter into the Philosopuy of Action itself.
In Euro-American Civilization it is impossible for us to find the Philosophy of Action, but in the Buddhist Philosophy, which Gautama Buddha has found in the Ancient India, has the theory of Philosophy of Action clearly, and if we rely upon the Philosophy of Action, the contradictory situations between Human Freedom and the Rule of Cause and Effect, can be solved exactly and clearly.
In the Philosophy of Action, our Action is always done at the present moment, and the Real Action is never done at any time other than the present moment at all. Therefore all human Real Action is always inevitably done at the Real Preasent Moment, and such a Real Present Moment is always so short as the edge of the width of razor-edge.
And relying upon such a fact that the Real Action is always done at the so short length of the Present Moment, and so Human Beings can select their freedom just at the present moment of Aeal Action.
