Immanuel Kant in 25 lines
Every Immanuel Kant passage in thinkr's library, with the theme each one speaks to.
“Two things fill the mind with ever new and increasing admiration and awe: the starry heavens above me and the moral law within me.”
“Science is organized knowledge. Wisdom is organized life.”
“Act only according to that maxim by which you can at the same time will that it should become a universal law.”
“Live your life as though your every act were to become a universal law.”
“The wish to talk to God is absurd. We cannot talk to one we cannot comprehend — and we cannot comprehend God; we can only believe in Him. The uses of prayer are thus only subjective.”
“Religion is too important a matter to its devotees to be a subject of ridicule. If they indulge in absurdities, they are to be pitied rather than ridiculed.”
“Freedom is the alone unoriginated birthright of man, and belongs to him by force of his humanity; and is independence on the will and co-action of every other in so far as this consists with every other person’s freedom.”
“Out of the crooked timber of humanity, no straight thing was ever made.”
“Have patience awhile; slanders are not long-lived. Truth is the child of time; erelong she shall appear to vindicate thee.”
“The death of dogma is the birth of morality.”
“As the analysis of a substantial composite terminates only in a part which is not a whole, that is, in a simple part, so synthesis terminates only in a whole which is not a part, that is, the world.”
“The mind intent upon resolving as well as compounding the concept of a composite demands and presumes boundaries in which it may acquiesce in the former as well as in the latter direction.”
“Percepts and phenomena which precedes the logical use of the intellect is called appearance, while the reflex knowledge originating from several appearances compared by the intellect is called experience.”
“The concept of space is not abstracted from external sensations.”
“The concept of space, therefore, is a pure intuition, being a singular concept, not made up by sensations, but itself the fundamental form of all external sensation.”
“A whole from necessary substances is impossible. The whole, therefore, of substances is a whole of contingent things, and the world consists essentially of only contingent things.”
“A spurious axiom of the first class is: Whatever is, is somewhere and sometime.”
“All natural capacities of a creature are destined to evolve completely to their natural end.”
“In man (as the only rational creature on earth) those natural capacities which are directed to the use of his reason are to be fully developed only in the race, not in the individual.”
“The means employed by Nature to bring about the development of all the capacities of men is their antagonism in society, so far as this is, in the end, the cause of a lawful order among men.”
“The greatest problem for the human race, to the solution of which Nature drives man, is the achievement of a universal civic society which administers law among men.”
“This problem is the most difficult and the last to be solved by mankind.”
“The problem of establishing a perfect civic constitution is dependent upon the problem of a lawful external relation among states and cannot be solved without a solution of the latter problem.”
“Is it reasonable to assume a purposiveness in all the parts of nature and to deny it to the whole?”
“A philosophical attempt to work out a universal history according to a natural plan directed to achieving the civic union of the human race must be regarded as possible and, indeed, as contributing to this end of Nature.”
Where Immanuel Kant lands on a hard choice
Quotation is the easy part. The harder test is what a position does when it meets a situation where every option costs something.
A friend asks if they made the right choice. They didn't.
You are treating your friend as someone capable of reality, not as someone to be managed. The risk is cruelty disguised as principle.
Someone you love is wrong in public.
You are loyal to the person's better self, not merely to their public comfort. The danger is humiliating them while congratulating yourself.
A convenient tool wants more of your attention and data.
You are refusing both panic and surrender. The danger is believing a boundary exists because you named it once.
You have to decide before you feel certain.
You are asking which choice can survive explanation to yourself and others. The risk is choosing the defensible path rather than the living one.
You are good at something you no longer love.
You are asking what excellence requires beyond mood. The risk is making duty a prison for an old self.
You were told a secret that is hurting someone else.
You are refusing to make your word depend on convenience. The risk is a loyalty so rigid it protects the wrong person.
A promise you made sincerely no longer fits who you are.
You are treating your past word as binding on a self that has changed. The risk is loyalty to a person who no longer exists.
A child asks a question and the true answer will frighten them.
You are refusing to train someone to expect managed reality. The risk is honesty timed for your conscience rather than their readiness.

Reading Immanuel Kant today
Immanuel Kant wrote in 1724–1804, from Prussia — a world with different assumptions about authority, death and what a life is for. That distance is useful rather than a problem: it is what lets the ideas cut against assumptions you did not know you were making.
In thinkr, Immanuel Kant is one of 44 thinkers you can put a real question to, and the answers come back in that thinker's own voice and commitments rather than as a neutral summary. The 25 passages above are what the app draws on.
