Not compatible; so differing as to be incapable of harmonious combination or coexistence; inconsistent in thought or being; irreconcilably disagreeing; as, persons of incompatible tempers; incompatible colors, desires, ambition.
Incapable of being together without mutual reaction or decomposition, as certain medicines.
An incompatible substance; esp., in pl., things which can not be placed or used together because of a change of chemical composition or of opposing medicinal qualities; as, the incompatibles of iron.
Injustice, poverty, slavery, ignorance - these may be cured by reform or revolution. But men do not live only by fighting evils. They live by positive goals, individual and collective, a vast variety of them, seldom predictable, at times incompatible. Isaiah Berlin
Disagreements between incompatible beliefs cannot be settled by reasoned argument because reasoned argument is drummed out of those trained in religion from the cradle. Richard Dawkins
A consistent anarchist must oppose private ownership of the means of production, and the wage-slavery which is a component of this system, as incompatible with the principle that labor must be freely undertaken and under the control of the producer. Noam Chomsky
It is clear to me that people often want incompatible things. They want danger and excitement on the one hand, and safety and security on the other, and often simultaneously. Contradictory desires mean that life can never be wholly satisfying or without frustration. Theodore Dalrymple
We must face the fact that the preservation of individual freedom is incompatible with a full satisfaction of our views of distributive justice. Friedrich August von Hayek
