Fundamental Constitutions of Carolina – Wikipedia

John Locke was a great philosopher who encouraged tolerance in his works, no doubt about that but many accuse him of being a hypocrite and racist who cared only for the liberty of English capitalists. These accusations are justified with the simple fact that John was a major investor in the English slave-trade through the Royal African Company.

Also in 1669, John participated in drafting the Fundamental constitutions of Carolina, a British colony in America at the time. The constitution did not depict the levels of tolerance advocated by John in his writings especially Article 110 which states, “Every freeman of Carolina shall have absolute power and authority over his Afro-American slaves.”

Lord Ashley was the most powerful man in England serving as Lord Chancellor of England but soon lost all his power and faced imprisonment because of his political views that resulted in Charles II disfavoring him.

Upon seeing the harsh fate his mentor encountered and fearing that he might suffer the same fate John moved to France in 1675. He returned to England in 1679 after Lord Ashly was granted restoration from exile. However, this was short-lived.

In 1683, there was an assassination attempt on the lives of Charles II and his brother, James. The Rye House Plot was uncovered to be behind it and this led Charles into running away from England again. Being a protestant closely associated with the Rye House John was suspected of being involved and as a result he took refuge in the Netherlands. He only returned to England after King James II had been overthrown, that was five years later. It is unknown if John actually participated in the assassination attempt but historians believe he was not involved in the plot.

John Locke was also impressed by the young lady and described her in a letter to a friend as: “The lady herself is so well versed in theological and philosophical studies, and of such an original mind that you will not find many men to whom she is not superior in wealth of knowledge and ability to profit by it.”

In 1691, Lady Masham invited Locke to live in her household in Essex which he accepted. John lived there until his death on 28th October 1704 when he was 72 years.

Locke’s theory of mind is often cited as the origin of modern conceptions of ‘identity’ and the ‘self’, figuring prominently in the work of later philosophers such as Jean-Jacques Rousseau, David Hume, and Immanuel Kant. Locke was the first to define the self through a continuity of consciousness.

He argued that at birth, the mind was a blank slate or tabula rasa. Contrary to Cartesian philosophy based on pre-existing concepts, he maintained that we are born without innate ideas and that knowledge is instead determined only by experience derived from sense perception, a concept now known as empiricism.

12. John Locke demonstrated the ideology of science

Similarly, John discovered the ideology of science whereby he observed that something must be capable of being tested repeatedly and that nothing is exempt from being disproved. He further stated that he always makes corrections once he discovers something is not true. This was among the greatest examples that Locke stood for in his development of the scientific theory.

13. John was very particular about his friends

Locke fled to the Netherlands in 1683, under strong suspicion of involvement in the Rye House Plot, although there is little evidence to suggest that he was directly involved in the scheme.

The philosopher and novelist Rebecca Newberger Goldstein argued that during his five years in Holland, Locke chose his friends “from among the same freethinking members of dissenting Protestant groups as Spinoza’s small group of loyal confidants. Locke almost certainly met men in Amsterdam who spoke of the ideas of that renegade Jew. 

He insisted on identifying himself through his religion of reason alone.” While she says that “Locke’s strong empiricist tendencies” would have “disinclined him to read a grandly metaphysical work such as Spinoza’s Ethics, in other ways he was deeply receptive to Spinoza’s ideas, most particularly to the rationalist’s well-thought-out argument for political and religious tolerance and the necessity of the separation of church and state.

In the Netherlands, Locke had time to return to his writing, spending a great deal of time working on the Essay Concerning Human Understanding and composing the Letter on Toleration.

14.  His religious mentors were theologians

With regard to his position on religious tolerance, Locke was influenced by Baptist theologians like John Smyth and Thomas Helwys, who had published tracts demanding freedom of conscience in the early 17th century. Baptist theologian Roger Williams founded the colony of Rhode Island in 1636, where he combined a democratic constitution with unlimited religious freedom.

His tract, “The Bloudy Tenent of Persecution for Cause of Conscience” in 1644, was widely read in the mother country. Its content was a plea for absolute religious freedom and the total separation of church and state.

Freedom of conscience had had high priority on the theological, philosophical, and political agenda, as Martin Luther refused to recant his beliefs before the Diet of the Holy Roman Empire at Worms in 1521 unless he would be proved false by the Bible.

15. John Locke invested in slavery although he spoke against it.

Locke’s views on slavery were multifaceted and complex. Although he wrote against slavery in general, Locke was an investor and beneficiary of the slave trading Royal Africa Company. More importantly, when he was secretary to the Earl of Shaftesbury, Locke participated in drafting the Fundamental Constitutions of Carolina.  

The constitution established a quasi-feudal aristocracy and gave  Carolinian planters absolute power over their enslaved chattel property. Further, the constitution pledged that “every freeman of Carolina shall have absolute power and authority over his negro slaves”.

Philosopher Martin Cohen notes that Locke, as secretary to the Council of Trade and Plantations and a member of the Board of Trade, was “one of just half a dozen men who created and supervised both the colonies and their iniquitous systems of servitude”.

According to American historian James Farr, Locke never expressed any thoughts concerning his contradictory opinions regarding slavery, which Farr ascribes to his personal involvement in the slave trade. Locke’s positions on slavery have been described as hypocritical and laying the foundation for the Founding Fathers to hold similarly contradictory thoughts regarding freedom and slavery.

Locke also drafted implementing instructions for the Carolina colonists designed to ensure that settlement and development were consistent with the Fundamental Constitutions. Collectively, these documents are known as the Grand Model for the Province of Carolina.

16. He was strongly opposed to atheism

John Locke was a fervent supporter of religion and a staunch opponent of atheism. In his view, it was important to actively oppose atheism in others while maintaining one’s own trust in God. Although Locke firmly believed in the value of religious tolerance, he maintained that atheism should not be accepted.

According to him, the mind is made up of a variety of linkages between ideas, and these associations might be neutral or adverse.

One indication of his views’ enduring influence is the fact that half of these books were published after his death. In the centuries since his passing, his writings—which cover a variety of subjects from philosophy to economics—have had a significant impact and have continued to influence how we currently perceive the world.

19. John Locke’s work had a profound impact on the world of philosophy

John Locke’s writings had a massive impact on philosophy, and geniuses like Voltaire and Jean-Jacques Rousseau accepted and refined his views.
