How did Justice Anthony Kennedy describe liberty in the Lawrence v. Texas majority opinion?

In the majority opinion for Lawrence v. Texas (2003), Justice Anthony Kennedy defined liberty as a concept that extends beyond mere physical boundaries, protecting individuals from unwarranted government intrusion into their homes and other private spheres.1

He articulated that "liberty presumes an autonomy of self that includes freedom of thought, belief, expression, and certain intimate conduct". Kennedy emphasized that the Constitution protects the right of individuals to establish personal bonds with companions, noting that the state cannot demean an individual's existence or control their destiny by criminalizing private sexual conduct. Ultimately, he described the case as involving liberty in both its spatial and "transcendent dimensions," asserting that the Due Process Clause safeguards these vital interests from government intervention.12
