Blaise Pascal

“The immortality of the soul is a matter which is of so great consequence to us, and which touches us so profoundly, that we must have lost all feeling to be indifferent as to knowing what it is. All our actions and thoughts must take courses, according as there are or are not eternal joys to hope for, that it is impossible to take one step with sense and judgment, unless we regulate our course by our view of this point which ought to be our ultimate end.”
