Where our knowledge of a cause is derived from our knowledge of the effect, which is falsely (I think) here supposed, nothing can be logically, that is, apodeictically, inferred, but the adequacy of the former to the latter. ❋ Henry Nelson Coleridge (1820)
Further, the moral law is given as a fact of pure reason of which we are a priori conscious, and which is apodeictically certain, though it be granted that in experience no example of its exact fulfilment can be found. ❋ Immanuel Kant (1764)
Either our proposition must be proved apodeictically; or, if this is unsuccessful, the sources of this inability must be sought for, and, if these are discovered to exist in the natural and necessary limitation of our reason, our opponents must submit to the same law of renunciation and refrain from advancing claims to dogmatic assertion. ❋ Immanuel Kant (1764)
When experience is presupposed, these principles are apodeictically certain, but in themselves, and directly, they cannot even be cognized a priori. ❋ Immanuel Kant (1764)
But the reason why this objection is so unanimously brought against our doctrine of time, and that too by disputants who cannot start any intelligible arguments against the doctrine of the ideality of space, is this -- they have no hope of demonstrating apodeictically the absolute reality of space, because the doctrine of idealism is against them, according to which the reality of external objects is not capable of any strict proof. ❋ Immanuel Kant (1764)
For he cannot pretend to any certainty of the non-existence of God and of a future life, unless - since it could only be proved by mere reason, and therefore apodeictically -- he is prepared to establish the impossibility of both, which certainly no reasonable man would undertake to do. ❋ Immanuel Kant (1764)
We cannot prove that this practical rule is an imperative, i.e., that the will of every rational being is necessarily bound to it as a condition, by a mere analysis of the conceptions which occur in it, since it is a synthetical proposition; we must advance beyond the cognition of the objects to a critical examination of the subject, that is, of the pure practical reason, for this synthetic proposition which commands apodeictically must be capable of being cognized wholly a priori. ❋ Unknown (1785)
This duty is founded on something that is indeed quite independent of these suppositions and is of itself apodeictically certain, namely, the moral law; and so far it needs no further support by theoretical views as to the inner constitution of things, the secret final aim of the order of the world, or a presiding ruler thereof, in order to bind me in the most perfect manner to act in unconditional conformity to the law. ❋ Immanuel Kant (1764)
But in the Critique itself it will be demonstrated, not hypothetically, but apodeictically, from the nature of our representations of space and time, and from the elementary conceptions of the understanding.] ❋ Immanuel Kant (1764)
