The first problem, as belonging to the critique of pure speculative reason, requires that we explain beforehand how intuitions, without which no object can be given to us and hence none can be cognized by us synthetically at all, are possible a priori; and its solution turns out to be that these intuitions are, one and all, only sensible and hence do not make possible any speculative cognition that would go further than possible experience extends, and that therefore all the principles of that pure speculative reason accomplish nothing more than making experience possible, either of given objects or of those that may be given ad infinitum but are never completely given.
