“Any voter with a healthy understanding of the flaws of human nature and who notices the vast amounts of money solicited and received by politicians cannot help but believe that we are unduly influenced by our benefactors' generosity,”
John McCain
“Human action can be modified to some extent, but human nature cannot be changed.”
Abraham Lincoln
“We need more understanding of human nature, because the only real danger that exists is man himself . . . We know nothing of man, far too little. His psyche should be studied because we are the origin of all coming evil.”
Carl Gustav Jung
“The only thing that one really knows about human nature is that it changes. Change is the one quality we can predicate of it. The systems that fail are those that rely on the permanency of human nature, and not on its growth and development. The error of Louis XIV was that he thought human nature would always be the same. The result of his error was the French Revolution. It was an admirable result.”
Oscar Wilde
“The science of the mind can only have for its proper goal the understanding of human nature by every human being, and through its use, brings peace to every human soul.”
Alfred Adler
“Love is the basic need of human nature, for without it, life is disrupted emotionally, mentally, spiritually and physically”
Karl Menninger Dr.
“Slavery is also as ancient as war, and was as human nature.”
Voltaire
