• Space is not empirical, must be presupposed.
• Space is a necessary a priori representation which underlies all outer intuitions (not a concept).
• Space is not a general concept of things in general, but a pure intuition.
• Space is represented as an infinite given magnitude.
• Space does not represent any property of things in themselves or in their relation to one another.
• Space is nothing but the form of all appearances of outer sense.

• Time is not empirical.
• Time is a necessary representation that underlies all intuitions and therefore is a priori.
• Time has only one dimension, different times cannot be simultaneous.
• Time is not a general concept but a pure form of sensible intuition.
• Infinitude of time rests on immediate intuition because each magnitude of time is possible only through limitation and therefore the whole representation cannot be given through concepts.
• Concept of motion is possible only through and in the representation of time.
• Conclusions:
  • Time is not something which exist of itself. It is the subjective condition under which alone intuition can take place in us.
  • Time is the form of inner sense, that is, of the intuition of ourselves and our inner state.
  • Time is the formal a priori condition of all appearances.
    • It has objective validity only in respect to appearances, not for things abstracted or taken in general.
    • The empirical reality of time is not absolute reality.
  • Time and space taken together, are the pure forms of all sensible intuition, and so are what make a priori synthetic propositions possible.
  • The Transcendental Aesthetic cannot contain more that these two elements.

• All intuition is nothing but the representation of appearances.
• We cannot know the object itself.
• As appearances they cannot exist in themselves, but only in us.
• It is important that our Transcendental Aesthetic be certain, not just plausible.
• intuition contains nothing but relations and since a thing in itself cannot be known through relations, we cannot know the inner properties of an object.
• This also holds true of inner sense.
• This is not to say that these objects are mere illusion.
• The pure a priori intuitions of space and time constitute one of the factors required for solution of the general problem of Transcendental Aesthetic: 'How are synthetic a priori judgments possible?'
